Can someone explain to me how it is that club promoters work? Back when I was living in LA, I'd meet lots of people who would tell me they're a promoter for club X, but I never understood how they fit into the business model.
The promoter is an entrepreneur, their product is the event. He or she arranges the venue, the performers, the advertising, etc and whatever's left from the door price/ticket sales once everyone's been paid is their profit.
Lots of people do this part time looking only to break even, in that case their profit is in the form of social capital.
