Any place that has room for six or more people is perfect for this type of class, and my liability insurance covers any facility where I teach. You can start one at your workplace, your condo clubhouse, your school, wherever you think you'll be able to rustle up enough people to make it a go (but here in the Tri-Valley area is best for affordable rates.)

Prices for classes in the Tri-Valley region range from $15 to 12 per-person for each class, depending on the location and number of people committed to the six-week series. Here's a promotional flyer that can be used to generate interest for such a class.
