Music Career Mentoring required

The guitar always fascinated me, ever since childhood. I took up playing the guitar as a hobby initially, but it became an obsession over the years. But the turn of events in life pushed me on to become an executive in an accounting firm for the last twenty years. All these years I never left the guitar and did whatever I could to improve my playing skills. I want to give up my job and want to teach the guitar to aspiring learners. I want some guidance as to how do I hire students and how do I run my school in a professional manner.
