Benny,
What I would do is get your best stuff together and pick out about 3 or 4 of the best from that, then let everyone here, or any other forum similar to this and let them tell you what you 'might' need to work on. (Before and after's)
I say that 'cause the real working world is full of people that really know their stuff, but on the other hand, there's a lot out there too that aren't as good as the people you'll find in any forum similar to this, meaning, some of these people that just play at it are as good as some I have worked with.
If you did retouching from home, that might be the best of the two choices for you, 'cause the real work envirionment isn't nowhere near as fun.
Working from home has it's advantages, and also disadvantages, but you can learn at your own pace, and learning all you can be a big asset when you begin looking for work at any company.
From 1996 to 2001 I worked at 5 companies (in the US) and learned a lot, but what I learned mostly was that I hated it, it definitely took the fun out of the job for sure, but the money was good.
That's over simplifying it really.
I spent a year after I got my computer learning how to use my PC, then, after that first year, I spent the next learning Photoshop, I had a friend that said he'd give me a job if I learned it well, that wasn't a problem, I LOVED Photoshop, I couldn't get enough, it literally changed my life when I first got it.
(My present job was being phased out due to computers)
I was given a job by my friend, and I couldn't believe that I was actually getting paid for something I loved, that was the first time in my life that I actually looked forward going to work.
My friend had told me to learn Photoshop, but he really didn't specify 'what' to learn, so I mainly played around in it and learned what I 'assumed' would be the stuff I'd be using, which turned out to not be true at all, and it was partly my fault 'cause I didn't know what to ask, but should've...
(This was before I was online, so I couldn't go online to search out how to do certain things, and I did my best)
To get more to the point, I found out that what I had learned wasn't really what was needed really, I mean, yeah, I needed to know it, but what 'they' wanted me to know, I had to learn at work, and fast too, 'cause they were paying me, and "hot jobs" were waiting...
During this learning process at work, I also had to learn the Mac too, which was fine, but it made learning it all, just that much more, but it wasn't too bad.
Retouching may be a general term really, here, I'm not sure about Australia, but it involves knowing, masking with Quick Mask, Paths, Curves, Unsharp Mask, the Stamp Tools, Layers, Layer Masks, Color-correcting, and of course a good working knowledge of Photoshop in general.
This was all much needed for magazine ad work for pre-press, etc., and you may be interested in working for something entirely different, such as a photography studio.
I had worked in printing for the past 25 years before this, so what I did now was nothing new to me, but it was definitely a new way to go about it all.
Another thing, in the business, you will more than likely still be working week-ends, long hours, and holidays, there's always "hot jobs" that need to go out, but that all depends on where you work, what kind of work you do, and what kind of place (read: bosses) it is...
I also had to take a cut in pay, about half of what I was making before, and I was able to swing it, and within about 3-1/2 years I was making more than I was in my previous job, which was really good.
That didn't last though, the crunch that the industry went through after 9-11 trickled down and I got out of working for someone else.
Actually, every place that I had worked for closed their doors for one reason or another, and the last place I worked laid me off right before, they used seniority as a way of laying people off, which was the fair way, but laid off I was, even though I was told that they'd rather lay off others than me, but I still think it was fair to those that worked there for years, versus my two.
I did end up free-lancing for a year and a half or so, which was REALLY good money, (about 4 times what I made hourly) but it was few and far between, my main bread and butter account lost their bread and butter account, so that stopped that for the most part.
I was really tired of looking for work way too often, so I went into business for myself, which was hard, but worth it, for a while at least.
(I worked 16-18 hours every day, 7 days per week, and that alone contributed to the inevitable burn-out in the years to come)
Again, I found myself thinking that I couldn't believe that I was getting paid to do work that I considered "fun", but a year later, I was back where I was, it wasn't fun anymore, having to deal with customers daily, consumed MOST of my time playing secretary, and what I do can't be shared with another, 'cause they'd have to know 'exactly' everything I did to answer questions, help out, and take orders, etc.
I couldn't pay someone, much less find someone to help me, so it was all on me, every day.
So, to shorten an already way too long story, although it might seem glamourous at first, (and it may be for you) there is a lot to be considered when doing this type of work, and everybody and their dog has Photoshop nowadays too, and there's schools that train, so that narrows the road to what you want right there.
The bottom literally dropped out for me locally in the business back then, and when I was looking for work, (before I went solo) I would've been paid almost what I started out in an hourly wage, meaning very little, like starting over again...
My thoughts on this is to first make sure you are good enough to hire, you'd be judged on how good of work you'll do, and experience, they may even have tests, one place I applied for had tests, which consisted of daily routine stuff for that company, and it had all of the above concerning color-correcting in it.
Know your stuff, ask around a LOT before jumping in, have people on the forums tell you the truth about your skills, and find out what you'd be getting into before this decision.
I'm not knocking working in this field at all, but I say all of this in hopes that 'your' hope's aren't knocked, with surprises.
Working in the field is a lot like being on a forum, you'll learn new things daily very fast due to other techniques that people know, so that's good.
If you can swing it, land a job, and work for (probably) a smaller amount per week, and not mind working week-ends (possibly), you might be happy doing it, you may not mind the same things that really bothered me working at these places.
Most was due to lack of good leadership, which was a constant thing for me, and others at ALL of these jobs, but maybe I was just unlucky, and I have always taken a lot before finally letting it get to me.
I'm definitely not trying to dissuade you though, but hopefully you can gleen something from this, mull it over and see for yourself.
I wouldn't trade what I did for the world though, it was a great learning experience, and I applied a lot of it to what I do today too, and hands on is better than any classroom to me, even with the bad elements I ran into.
This is of course, all besides 'how' you learn 'what' you learn, there's lot's of people here and places online to get that info... meaning courses/training, etc.
Sorry about this being long, sometimes I like to type, and I kind'a overdo it...
