Before you choose what price to charge for your stage show, spend some time thinking about the value you bring to your clients.  Pricing tends to feel pretty straightforward to folks, while value can be a better more difficult to qualify, but it's important that you work out some level of appreciation for the work you do as a hypnotist.  Why?

Because at some point, a potential client is going to ask you to justify the price you are charging.

That justification should not be a canned response like, "That's the standard in our industry." Your response should be a confident, heartfelt answer about the value you will bring to them.  When you communicate that, the lead will be more likely to take action and choose you.
