I had a friend who organized these kinds of events. She made okay money for the amount of time invested in the organization of the event itself, but events were sporadic, and once you considered the time investiture in getting the event, a retail job paid rather better. If you can achieve the kind of success where people seek you out, it would pay pretty well, but that requires considerable social capital and skill, and there are other opportunities where similar social capital and skill would pay better.
