Football Pick em Game

I need a web developer to help me with the programming part of a football pick em game site. Basically the game will consist of players signing up, then weekly picking the winners of games. Each game will have a points value assigned to it. If the player correctly picks a game, he gets those points, which accumulate on a leader board. I as admin, would log onto an admin page and fill out the games for the week, plus the points value of each game. I am a designer, and can handle that end of the site. I just need help from a developer for the database and dynamically updating part of the project. My partner and I would like to involve the developer as a 1/3rd partner in the site in exchange for the work although we are also open to simply paying for the work on the project.
