This is what you may look into as a start.
But, I am sure you cannot just go to and event and start taking photos and sell. I am sure you wouold have to get in touch with people running (producing) the event for permission or deal to give something to them $$$f. So, here it is:

I recall reading an article, I think it was even in Shutterbug a few years ago about a guy who did weddings that way, printer on the go. In a not to subtle way, he was saying when folks had a few too many drinks and credit card in pocket, there were more likely to spontaneously purchase if they could see the finished product. By the way, cruise ships use this tactic all the time, nothing wrong with it. I will never be a wedding photographer - too hard - but if I were, I can guarantee you while I was shooting, my assistant would be cranking out prints of what I had shot and displaying them. Heck, I'd make sure I brought a number of frames for the 8 by 10's I'd probably crank out - credit card or cash only, or ATM.

Some others that have shot at outside venues find the most critical piece of equipment is the cheapest Honda generator to run you printer, its quiet - very critical. I'd minimally have a large tent of some sort, tables, display areas, generator and a couple of printers with lap top or two, now I'd probably use a few net books (cheaper and amazingly able).
