I had a school running for 8 years. We shut it down and opened back up five years later. The day we opened, we got 12 of our old students back, and a bunch of new ones. I offer classes 4 nights per week, plus a 2 hour advanced class once per week. I have 22 years total MA experience. I have a 3rd degree black belt in American Shotokan, (AIKA certified) and a 1st degree in TKD, (also certified). I offer free seminars twice per year from various experts in their field, which is usually pressure points, or ground fighting, and I charge $55.00 per month. I feel that this is a good deal for what you get. I don't make much profit, but the school pays for itself, and the students are happy.
