Expect to do some footwork on this. It starts with you, what sort of camp experience do you want? What do you and your group like doing? Would you rather help more or pay more (although, that's not always how it works out.)
go through the camp list and find a list of "hot prospects."
At that point, write a one or two paragraph synopsis of what you offer and what you want. Send it to the first ten or fifteen camps on your list. Some of those camps will be friends only, some won't be going to the playa this year, some will be filled with crazy idiots who would give you lots of stories to tell, but not the kind that are fun to live through.
Go through your responses, ask more questions, answer the questions they ask, and see what seems to be a good fit.
And feel free to read this thread to get a lot more pointers.
