This is a huge enterprise that could be duplicated using a different product, he has pretty much made it impossible to enter this niche because he will drive pricing down to force others out of the niche. The key to duplicating this model would be to find a product that you could buy inexpensively, sell for a low margin then scale through various distribution channels.

If these people were really friends it would not require money for them to give you insight on how to make money they would give freely of themselves.
