Ok. Future reference! you need to know what you charge, why you charge it, and have the means to show images that prove that you
deserve the money that you charge. Until then you my shoot for free.
Do some research on what albums cost and then offer them to them. I would not charge them anything for your time. If they want an album then tell them the amount and thank them for letting you learn with them.
The first 3 weddings I did for free but I had already researched albums, custom cd's and much more. I had a slight mark up but it was not very much. The first album I sold cost me 120 and I charged 175. I did not tell them the 125 part. Now if I was to do a wedding some of the albums I make are up to 400 and I charge around 800+. Everything you offer you need to know about before you take a picture.
Good luck and do some research, there is a ton out there!
