I teach large organizations that book be months in advance. My contracts are six month to a year. I do find from time to time that i can hold a section of a group. To get me to teach a person would cost me a lot as I am custom teaching classes of 25 or more at a time. When not teaching I would be in the field getting future clients. so I have had to charge a premium for my time. It takes the same effort for me to teach a one-on-one as it does for a large forum. I charge $400.00 for a one-on-one availability for my one-on-one is subject to each case and my calendar so if you need a class tomorrow then I am not your guy.
I find my time to be limited and valuable. I charge $400.00 for a one-on-one class
