John,

I'm doing weddings on film and what I have found is that I make more money per hour.

I made the decision that my job is to shoot and keep the shot count much lower then you suggest, <250; I'm truly after just keepers, then the lab does the rest.

I get paid nicely for my time there, the client pays all processing costs on top of my fee, $50 per roll including proofs and scans.

Simple quick and done.
