Looking for a script/theme for contests



I am looking for a script/theme with which you ca build a website like 99designs (but with different type of content, not designs).

The contest owner pays an amount to post his contest, users submit their entries and in the end, the contest owner chooses the winner (the winner wins the money)

I am definitely sure I’ve seen on the market something like this, but I don’t find it anymore, if anyone could help me…
