What's expensive to you? Where are you/is your wedding located?
We spent like $600 to have someone take pictures for 3 hours and they gave us a set of proofs with that price. We bought a few larger prints and albums after all so our total photography price was more than the $600 in the end. I thought that was a great deal though for what I was looking for. We went through Kemmetmueller Photography in Deephaven,
Kemmetmueller Photography.
Our pictures are fantastic, if I do say so myself!
I would recommend you think about who will be photographing your wedding. The day goes by in an instance but your pictures will last a lifetime (I know corny, but true). My sister-in-law had a friend of a friend type person take her pictures because she was inexpensive, and now she says the one thing she would have changed was spending more on her photographer.
Good luck!
P.S. If you can be more specific with what you are looking for and photography budget I might be able to help find you some ideas.
