This system has allowed me to quadruple my business. We started with the minimum trial membership and now we have been able to quadruple business to over $100K per year. What started as a neighborhood hobby is now a regional enterprise. Could not have done it without this system. Now running 5 schools and 8 instructors and growing every day. Booked solid 90 days in advance- everyone prepays. PayPal loves us. Don't ever change. You would put me out of business. Don't tell my competitors!
