Nurse Practitioner Schools

I am a nurse and ready to go to school nurse. I'm more interested in the medical psychiatric nursing program, but certainly not if there is a need for psychiatric nurses. My reason for wanting to psychiatric nurse is that I have the opportunity to start a program for people who need psychiatric treatment, I can write books about self-empowerment, etc. I want to nurse program because it is more economical family safer. Period. A person can go anywhere and work as a nurse in the family, but if they do the studies are somewhat limited in the income they earn. I appreciate all the advice he receives. I would also appreciate any information about sites that provide statistics on the demand for professionals, especially psychiatric nurses.
