Haha, you can explore all of these on the freelance sites (like getafreelancer).
"Hey, send me 10 sample before and after retouches, 1000x800px size, I am a great photographer and will give you a lot of work if I approve it."
"Here is a photo for you to restore, restore in the next 6 hours and send it back, we will give you a lot of work later"
"Dear bidders, I need to get this photos cut from the background for maximum 0.5$ per photo. Happy bidding."
Am I sick to see that. But a lot of people catch on this. And they send samples and they work almost for free. It's sad
