@BPH first off I think this is great and wish you the best of luck!
Second and not to throw a wrench in but
did you research the legal aspects of this since you're charging a fee for your services?
Here in California (and other states) by law one needs a license or permit, even selling something on the street for money requires a permit!
I know this because I was required to apply for and obtain a permit when selling some home-made food items and various handmade crafts at the Farmer's Market. I was surprised I didn't think I would but yep I did!
Here your selling your knowledge, expertise and coaching services for a fee, no difference.
I just don't want this to come back and bite you later if you didn't, that's all.
But again sounds great! A win-win!
