Apply to present at major conference such as IDEA, AFAA, AAHPERD and state HPERD, etc
Become an AFAA and ACE continuing education provider.
Give workshops in your own club and invite other clubs. This is how I got started over 25 years ago
I barely teach group today because I do a lot of teacher trainings (group and 1-on-1 training). I make more money and it’s less wear and tear on my body
