I just got Professional Tarot and I am really enjoying it. I thought her ideas about marketing were excellent, I'm studying marketing in school and have noticed that many tarot readers have no idea how to sell themselves.
I felt that the book was very thorough as far as giving practical, ordered directions. There is plenty of info about setting up vendor accounts with banks, being able to accept credit card payments, and legal issues. I had been worried that it was going to mainly consist of fluffy "do it the way you want to" sections that leave you with a lot of questions.
I liked the sections contributed by Diane Wilkes. I'm a fan of her website and have enjoyed her articles before. She had a lot to say about telephone tarot and tarot ethics.
I would recommend this for anyone who has been todl they should charge for their readings but have no idea where to start.
