I see that sometimes for ballroom classes, but not for latin dancing.

If there is no such dance class in a metro area of 200,000 people, you should probably rent a building, hire a teacher, and open a dance studio.

Try community colleges and local YMCAs and recreation centers. Dance studios are often much more expensive. $15 per group lesson is pretty standard around DC.

I bet you can find a partner to bring, if you're willing to ask a woman whom you consider below your dating standards. There may be resulting complications, so use your judgement.
