My husband photos our sessions. He also has many published photos of models he worked with over the years. As for hiring him, or anyone else, to photo a session of IR sex, I just don't see the demand, frankly. However, IF that isn't enough to dissuade you from pursuing the possibility, I would say work up photos of shoots the photographer has done already - ensure you have the model's releases on file - send said portfolios to some of the GB group organizers as well as some of the profiles of people you've scanned and would like to work with them. In other words, create a demand for the services of a photographer vice a husband or idle participant from the event. If you're fortunate enough to get a response, have a price list worked up already and ensure you have signed model releases, too. Depending on any addendums to the model releases required by the "models," you now have a "stock" of photos to market. Best of luck.
