Surreal and emarts, your work is excellent.
Here, in the USA, there is the American Photographic Artisans Guild (APAG). Their website is
http://www.apag.net/. They specifically try to recruit digital retouchers. However, most of their membership is focused on the restoration and artwork. They are trying to capture the commercial folks like yourself, but I don't think it's working out.
They are trying to do things with accredidation, education, etc. It's good, but I think they have alot of baggage from the manual retouching era. Although that is an awesome aspect of our history, we need to let go of our inhibitions and pass the torch. Many highly skilled manual retouchers got dumped or ignored and our industry is suffering (almost anyone with Photoshop can claim to be a retoucher).
A person can't just run out and open a clinic and claim to be a doctor. You need education and licensing. So it should be in the graphic arts world (especially retouching). Because this has not been the case, the quality of photos and design in general has been going down. I'm not saying I'm anything great (I have a long way to go). But I have observed the trends since 1999, when I changed careers from photographer to retoucher.
Regardless, professional retouchers--those who make a living fixing and enhancing photographs--need a guild, union, association or whatever you want to call it. It could be international or national. There's the

Let's all stay in touch. You never know what may happen.
