Coaching for parents and high school students

I am a former high school counselor. I resigned to counsel/coach on my own.
I am not sure how to get the word out to my clients. I’m great at what I do and I’m very good at designing and delivering great content as I did it often for Southlake Carroll ISD as a former teacher and counselor. I offer classes at a local center. I still don’t have enough clients but i know there’s a HUGE need with people that will and can pay. Please help me figure out how to get more parents and students using my service. Thank you Danette
