All I can say is research. I'm a wedding photographer and it is really difficult to come up with pricing. A lot of time is spent figuring out overhead, how much time will be spent meeting, editing, and any other photo process, and how much your art is worth. All in all I make maybe minimum wage - $11 an hour.
