Ideas

I heard about people doing this for Katrina victims that had water damaged photos, if it hasn't been done it sounds like a go for sure.

Could even be tied into classroom activities --
Middle School, high school, and college students who are taking graphic design classes, and learning the ropes of photoshop --
could help others out, and earn a few bucks while doing so.

Bravo!

I think this is a great idea, and would be pretty useful.

I could see it being extended to include photo retouching on just plain old "bad photos" done by people who didn't know what they were doing, but had a fundamentally good shot.

I can see how this idea would prove useful. However, I doubt there are that many people who are in desperate need of having their photos repaired. I don't doubt that there's a market for this, but I'm unsure whether the market is big enough to warrant spending the cash to get such a site up and running.

If multiple people work on the same image, the requester could perhaps view a sample (scaled down & watermarked) of each users work then pick which he/she thinks is the best.

Good idea. It's the sort of thing where you could a lot of business very quickly with a lot of small transactions. Could possibly integrate with flickr.com, and/or give the option to send hardcopy prints to the customer (via Kodak for example). +1 from me :-)

But it can actually be just a part of grander scheme: Pimp my Photo. ;)

You have people posting photos, you have other people doctoring them in different ways.
