I think it's pretty hard to break into this market as most of the big players are already over-saturated with photographs in most standard categories. It might make more sense to focus on a specific subset of the market that's under-represented (shots of people doing activities, etc.) or local news events. Also given your audience you might need to be extra careful with model releases, because if the people in the photographs are minors their parents will have to sign a model release and not the subjects themselves. The pricing seems off as well, if someones going to pay for a photo they'll probably be willing to pay more than $1. Also if the photographers are only earning $0.50/cents and only a tiny fraction of photos are actually sold, I'm guessing your photographers will get frustrated with not earning money quickly and leave your service.
