Planning irl tournaments in Sydney, would like your input =]

Hey all, as the title says, I'm planning some irl tournaments in Sydney and I'd like to hear your thoughts on how to go about things. For some info on what I've got planned, I'm offering OU and a custom format that generally resembles ubers, as well as VGC, but these are all subject to demand (if no-one's interested in say, RBY, I won't host it, instead I'll just be sad). There will also be cash prizes on offer.

If this interests you I've just got a survey to go along with this. None of the questions are required, but every answer is greatly appreciated. Thanks in advance!
