What is the average yearly income for Equine Mage Therapists?

Pardon me for saying this but there is no money in that field whatsoever. It is just a course that anyone can take that you can get license for. There is no practice to or specialty. Mage Therapy can be taught to anyone really and tons of large barn owners already now how to do it. I'm sorry to be blunt but it is more useful for common knowledge then a career.
