I'd say, start small. Maybe just a local cruise to a restaurant. Do a little show and shine in the parking lot. Use that opportunity to pick some brains, gather some help, and grow your base from there. It will give you a better idea of the logistics and promotions involved. It's not a huge deal, don't get hung up on the small stuff. Cross promotions and sponsorships are a big help for filling in a larger event, but not necessary for small ones. Build an email contact list, and keep in contact just enough to not be an annoyance to your base. I used to throw raves in the nw oregon area, not quite the same, but the event planning aspect is applicable. Good luck.
