A few years ago I was working with someone who was doing it-- she loved it and was doing very well. Unfortunately, I lost touch with her and at the time, I didn't quite get it. I wasn't understanding what exactly she was telling me. She was kind of vague, I think, because Admin didn't really want her to talk about it much.
A local CPA I have contacted has told me one of his clients does this and is very successful. I am hoping she will contact me and "talk."
There are groups and books which people can join or buy -- but I am trying to go it without having to buy it . We'll see, I may cave...
My biggest problem right now is trying to figure out possible "contract issues" and I haven't had much feedback on the other area. ( yes, an organization or book would help with these issues!!
Good luck, if I hear anything from the CPA client I'll let you know...
