This won't answer your question exactly or specifically, but I was recently playing around with a cost of doing business calculator. I was mostly just playing to see what it would take if I ever decide to work for myself. I filled out all the boxes to a bare minimum, and it said I would need to make about $700 a day to be able to cover costs and get a salary around 40,000. If you assume that the numbers are right above, then 8 hours of shooting time (this sounds reasonable if you include pre-sessions and stuff) and 20 hours editing, then that is 3.5 days. 3.5 days at 700 is about 2,500. I can easily see where adding a few more (probably realistic) business expenses and wanting to make more money, you can get up to 5,000 pretty quickly. Also, in my experiences, the $5,000 wedding are the fully-loaded weddings, and people seem to spend closer to the 3,000 to 3,500 range. ***I was using the NPPA calculator, which got posted while I was typing.
