Hypnotherapy can cost anywhere from $60 to $500 per session.  The price should be based on education, experience and ability.    I keep my prices at an affordable level because I want everyone to be able to afford the help they need to live better and be happy.  
I encourage the client to do their research and make sure you do not hire someone that took a 3-month course and can read a script.  Make sure your hypnotherapist has training from an accredited college and has learned some psychology.  Many licensed professionals only get about 40 hours of hypnosis training.  As a graduate from Hypnosis Motivation Institute, the only nationally accredited college of hypnotherapy, I graduated the first year with over 2100 hours of class and clinical time.  In the past 3 years I have done over 5000 hypnoses sessions.  Book your session now and experience first-hand what it is like to take control of your life.
