Sport prediction script (plugin?)

Dear developers,

I want to create a sports prediction website where the visitors can enter predictions on different sports. The first sports we want to start with are soccer and cycling. So the website has to have the functionality to create pools (and rewardings systems) for different type of sports.

The players should be rewarded with points, and the visitors can exchange their points for product prizes in our store.

Please contact me via profile page contact form, We need to develop sports prediction website with plugins/component for soccer and cycling. I can help on this.
