family portraits

How much should I charge for family portraits?
I have a few years experience in photography and was asked by my boss to take her family Christmas photos at the beach. I was planning on shooting a couple of rolls (yes I shoot film) and giving her all proofs in 4×6 prints. I use a Canon Elan and will use professional film and a professional lab. I usually just charge my friends for processing, but would like to make a little $$ this time:)
Are you ready to be your own boss? Then remember he knows you are not a pro yet, so why should he pay you like you are? Think of this as a friendly shoot. My thought would be to charge him for all the lab work + $50. Be fair you will still have to work for him until you turn pro.
