poll testing

I am thinking of doing a new contest for high school students to win a free Senior portrait. I am still working on the details and I am trying to figure out a way to conduct the voting.

Normally I would use facebook but they changed their rules and contests on facebook are now not allowed with out paying them $20,000 in advertising or something like that. Im not ready to do something like that. :D
