Facebook Game for Brazilian users

I need someone to develop the code to a facebook game, similar to "Song Pop"; but without any media, just questions. I will provide the Flash interface and the developer will do the code to make it work. - The player will be able to send questions to another user - The player will choose the subject, and then select some questions - The game will have some rankings and will publish it on the players' pages. - The player will be able to "buy" more questions (online payment) - I must be able to add more questions and subjects anytime, easily. Other features could be discussed with the developer, by PM.
