I would suggest that you do not stray too far from your wedding hourly costs. While I am not a professional, I am sometimes amazed at how much a photographer costs. My brother and I tried to hire one for my parent's anniversary - it was obscene how much the prices were. The fee to come to a restaurant was 400 dollars for 2 hours -with another $400 dollar minimum to be spent on photographs. I might add that the photographs were not cheap either.
