What is a fair price for my services?

Recently a friend of a friend reached out to me after seeing some photos of mine. She liked my work and asked if I’d be interested in shooting her parents vow renewal for about an hour. I accepted the job and told her I’d get the pricing to her within a couple days. This will be my first time shooting a vow renewal. Due to the fact that I’m still an amateur, I want to give her a fair price without making myself sound cheap. At this point it’s not about how much money I can make doing odd photo shoots, it’s about getting some experience under my belt and getting my name out there. I considered charging $75 for the hour, including the disc of edited images. If she wants prints, that would be additional. Is $75 a fair price? Too much? Selling myself short? What’s your opinion?
