Ok, so a friend of a friend wants me to do some pictures for her. She is a singer, who apparently was/is famous-ish in the UK. I'm not sure exactly what she wants to use them for, but I need some help with what to charge. 25 dollars per hour is my standard for the shoot, and a CD for getting personal prints. How much extra would you suggest if she wants to use them for publicity reasons? And what other permissions should I allow/disallow her to use them for?
