Basically, Jay already has a prime example of a client he trained who had incredible results.
Jay as a "guru" in a year or two?

YES! Jay woudl be an excellent guru. Imagine Jay changing BBers 5 grand a month - each - and moving 5 or 10 of them into his house.
Eat with them, train, pose, etc... teach them to blow up like he did. WOW he would be an excellent guru.
