Hi, all
Recently I've made a 30 second custom music for a tv spot. I didn't know how much to charge, I didn't have much time to think and had no one to ask, so i told them the amount I thought was fair ($3,500). They took it, i did it and they loved it.

Here are the questions.
1. Is the price too low or too much? Why?
2. How much would you charge? (please tell me what state you live in.)
3. Is there normal rates I can go by?
4. Do you have anything else you think would help me and everyone in this topic?
