Pricing is relative to your location and what you offer.
Things to consider:
1. What is the average price of similar programs in your area
2. What kind of experience do those instructors have compared to you
3. What is your overhead/how much do you have/want to make
4. Would you rather play the volume game (cheaper but bigger classes) or quality game (more expensive, but more intimate)
5. What can you offer that the other places can not
Based on your answers to this you will know if you can price higher then the others in your area, the same, or you need to go lower. My true advice is to charge what you think you are worth, offer things no one else can, and make sure you are offering the best product and customer service in the area. This is very much a you pay for what you get industry, do not under sell yourself.
