Just a thought - but perhaps instead of having a goal of being the highest paid trainer in NYC consider creating a business model to become the most sought after trainer in the country.

If you attain that goal, I'm pretty confident you can charge whatever you want.

To do so you'll need to have a deep understanding of your market. And you'll need to create an irresistible offer.

A good PR firm can help get your offer / USP / message out to the market. But until you have those things in place - until you have a business model - in my opinion you are putting the proverbial cart before the horse.

[Of course, you may already have those things in place (your question and the context you provided are absent those pieces)]
