I am looking at offering Proof Sets with my wedding packages does any one have any advice on this? Where to get a quality proof book, or if this is even a good thing to offer. Thanks :)

Being new to this idea of getting payed to take pictures. I Have some questions as to how much should I charge. How should I come up with a price? I am doing a wedding, a senior portrait, and School pictures for a small christain school. Any advice would be helpful.
