That's great luck. If people are interested in more swarms, try hooking up with some local pest control outfits. Once you become affiliated with one, the calls just keep coming in. I subcontract for Terminix, and a couple of other larger local outfits, and in season, that's where I get my cutout and swarm calls.
There's also a free site you can register with: Bees-on-the-net.com. I've gotten lots of calls from there too. Good luck!
