Hi,
Well, I've been a customer of Bill Sjostrom in the past and I know he sells a booklet or course on this...did you know?
I could not remember his website, but a little research dug it up:
http://wgsc.com/
You will see by scrolling down on his front page that he does sell this opportunity. The only problem that i see is that he has offered it for at least 2-3 years. I called around before to dentists & all either had someone coming to get their equipment already or one even did it themselves...(Hey, I guess that's how a Dr KEEPS all that money ~lol~)
Hope this helps!
Bea
