I think your biggest two things will be design and ray. Youll obviously wanna choose something good enough to grab peoples attention...deadlines...drawing dates...and ability to monitor who paid what efficiently. You should be more than fine for what you're trying to do. Btw do you have the pure leos from the litter you said you were going to grow out or would one of those be a part of the raffle? Sounds very interesting. Gl with it!
