Are you in HS or College?
If you're in college then talk to your student life people/ whoever provides money for that kind of stuff and get way more people to help than you think you need. of and free food always makes people want to come watch/ help
if you're in HS good luck. Chances are you'll have to fund it yourself, but you might be able to get them to help if you go to a small enough school. But again, way more people than you think you need. Oh and the more formal/legitimate you make it seem, the better chance you have of being successful.
