How to start up a Equine Assisted Therapy for Troubled Teens?

I'm working on a exam for a Business Course and my last exam is making a business plan of something. I would like to do it on Equine Assisted Therapy for Troubled Teens and Hippo Therapy for Adults and Children. I am trying to find someone who either runs or know a great deal on this subject to speak to.
Thanks

Answer: 
this can be a truly successful business module. I know horse have healing abilities .. and there was so many case of say autistic cases treated with horse back riding. but how come you thought of a hippo ? I would like to discuss that with you more if I may.
