We are looking to build a Facebook Roulette/Contest Application that must follow these conditions:
-The user must like our page to go to the application
-The user must subscribe our newsletter to get a ticket
-Each ticket is going to one person. One can increase the number of tickets if he invites other people.
-After the page reached 500k likes. Tickets are sorted to offer the big prize.
We are not sure if this is possible at all; therefore post on your message how do you intend to build this app.
Some design skills are very important.
