I'm sure it wouldn't be hard to find simply a Jiu Jitsu gym. Or a boxing one. Or like my friends in MI did they just made their own. Couple of them are very knowledgeable in different styles of martial arts and have since moved the gym to a hotter spot due to everyone wanting to join to either fight or stay in shape.
Perhaps if you can't find one close by, you and some friends could go that route and hire someone a few days a week to instruct, or maybe talk to some nearby gyms and see if they can work something out.
