Time for money

I love your podcast about not thinking about trading your time for money instead shifting it to providing value. I own a massage clinic and make a great living, but I want to make more. Since I am currently paid by service hour, I am getting stuck on how to apply that to my business. I dont make money unless I am working on someone. I feel like my income is tapped out by how many massages I can provide. I would love your thoughts on how to change that.
