You don't have to use their program, just their methodology.
In a nutshell: Start with a good location, Advertise, pick a rate and an ideal number of students. Know what level you need to be at in terms of number of students in order to make your bottom line. Organization and structure are keys to success.
Create a variety of programs. Kung Fu can be broken down to many: Beginner and Advanced, San Shou, Forms, Weapons, Chi Kung, Tai Chi, Traditional Medicine and Herbology, competition prep, self defense, childrens, lion dance... Have a store in your building.
Also, create a limited teaching program for your advanced students with discounts given to students for teaching and assisting (all the way up to free training).
Now define start and end-times for these programs. Be prompt with starting and ending.
Promote a trusted student to business manager (pay that person something). Have students enroll, have a website, have a newsletter, offer bonuses to students who bring friends. Have the business manager call students who were with you and may have dropped. Have the business manager watch billing and collect promptly.
