Perceived value determines whether you are worth your asking price. Everything you do will either increase or decrease your value. The more value you have, the more you can charge.
Be aware of the places people see you perform at because it can hurt of help you.
Learn how to answer questions like:
"Where do you perform at"
"How much do you charge"
Use techniques during a performance like a short intro that increases your value.
And get lots of testimonials.
