328757 NFL Pick'em ATS

I'm looking to create a site for my online NFL pick'em pool (1 league). I want participants to be able to sign up, make their picks, and be able to change them anytime during the week. The interface should be similar to Yahoo! Football Pick'em I also need admin features to be able to change the games/spreads as well as manually edit standings if necessary. I have hosting (PHP/MySQL) ***Here are my terms: - No money down - 50% of payment made when programmer completes 25% of project - Balanace paid once programmer completes 100% of project
