Where can I go to school to become a professional dog trainer?

Okay, I'm looking at protection dog training, because I love schutzhund, dogs, and have no problem being the decoy. I'm 17, female, and diabetic. I enjoy doing the bitework and just being around dogs. I'm from Nebraska, so I'm looking for a school for dog trainers either in Nebraska or Iowa. Is there medical insurance if I work with places that professionally train protection/law enforcement dogs? I want to do protection dog training, then go to school to work with wolves in Ely, MN at the International Wolf Center. Plz help?
