Giving away chocolate and munchkins at a live tournament as a prize is one thing, but in this instance it can't be done in a way that won't compromise someone's personal information and/or result in a direct exchange of currency. Neither of those are good ideas since we are a safe, non-profit community. Giga is 100% correct, if I have to be blunt with you. Contests are just difficult to host since there isn't really anything that you could give away as a prize.
