I would do that job for $400.
1 hour travel time
3 hours shooting at the ceremony/reception
2 hours of basic PP (skin smoothing, spot removal, minor adjustments), giving about 8 photos suitable for printing and framing
Remainder of photos burned to CD
A recommendation of where to get quality prints (not BigW)
Comes to $66/hour. Better than stacking shelves or mowing lawns for pocket money!
But, this assumes that i already have the appropriate equipment, and that i'm not relying on it as a primary method of feeding my family. I'm not factoring in a whole bunch of other expenses that come with running a business. It is based on not being a full time working pro photographerm which is the category I think the majority of folks on this website fall into
