well sites are VERY easy to build once a good database of galleries & thumbs exists
the problem would be setting up the trades. an average of 20 trades per site x 100 sites = 2000 trades just to start with.
maintaining a site at 10k is pretty easy. maintaining several sites at 10k isn't very difficult either. but maintaining 100 sites would probably be nearly impossbile. my guess is you'd end up with a small handfull of sites a little over 10k, about the same at 10k, and probably another 80 sites at 1-3k that you'd never have enough time to grow
