How would somebody get started in trying to making a living being a club promoter? Any tips?
Ok, so you're 17, that means your options will be limited.
Try contacting some clubs & find out what they pay for putting up fliers, distributing them on cars, etc. Thing is, you're young, you'll need to both get some experience, learn what the club industry people want, stuff about the business, AND develop some contacts :)
So start simple. Then, as you learn more, you can do more.
