Step by step.
One of the challenges marketing something like Qigong is educating the buying public. You just can put out an inexpensive book or tape and expect any results on something people never heard about.
We send out hundreds and hundreds of thousands of free video tapes to small segments of the population we feel would buy the course.
Eventually, the small buying percentage will increase because of word of mouth, radio, and TV advertising, news reports etc, which will make a lower price possible.
Chunyi Lin is also writing a book now for the book stores. This way people who learn about Spring Forest Qigong and cannot afford the courses will be able to receive benefit from the book.
There is a small army working to develop, publish, and market Spring Forest Qigong, which costs money.
As far as moving to the next level, talk to your library. Many purchase the course for their patrons. (Churches have also.)
Other people are buying in small groups and sharing the course and the expensive.
