Looking for an affiliate program for my FaceBook page

Hello!
I have a facebook page with 50k+ followers and i would like to find an affiliate program where my followers need to enter their email for a chance to win (money, gift cards etc.) and i would get paid accordingly for each submitted email.
My followers are mostly based in US,UK and Australia.
Do you have any suggestions?

Thanks in advance

Such model is named Sweepstakes SOI.
