I hear ya! At first I had such a hard time charging this, but I am actually middle of the road on my pricing-
I know artists who charge up to $350!
Sounds crazy, but last year at the USAs I had NINE girls to do and after expenses and paying an assistant a small fee I went home with less than $150 in my pocket.
I do this because I love it and I love making connections and helping the girls to feel beautiful and confident on stage.
