Well, something you can do is look at other photographers prices on their website to get an idea.
I used to work at Sears Portrait Studio and their prices ranged anywhere from 99.99 to 379.99 in their packages. They charged 7.99/sheet for loose prints (4-3x5, 2-5x7, 8-wallets, or 1-8x10) and more for the larger sheets. if they were edited in anyway, they add on an additional 7.00 to the price of the sheets. in the packages though, their enhancements were free. They charged 14.99 for a session fee (anywhere from 15-30 minute sittings).
Now in their packages it was like this:
10 sheets, 1 10x13, 1 collage would run you 179.99
15 sheets, 2 10x13, 1 collage would run 229.99
25 sheets, 2 10x13, 2 collages was about 279.99
it was something close to that. its been a while so i cant completely remember.
the only reason i am telling you all of this is to give you an idea of packages and such.
being a solo photographer, many of them charge alot more than some department store studio because they have a much better quality.
I hope this helps some though.
