Get people talking about you! Consider approaching prominent public figures, like the mayor, school principals, on-air media personalities, and get them to sing your praises.
What about the medical/wellness community? Could you work with doctors and other therapists to create a network of support for people who need your skill set?
Also, what about partnering with the sport/athletic stores? Offer training, seminars, assessments. Maybe link it somehow with the events you’re already involved with?
