I recently started doing some location work for a local radio station. Part of the deal is for me to record the shows and mix for broadcast. Like most things, it always takes longer to get the mix wrapped up than I expect, so I spend more time on the mixes than I quoted. If I'm charging a fair price for the work but am just slow, then I'm OK with that, but if my productivity is reasonable, then I should be quoting more time for the jobs. Just to set the scene - small venue - a restaraunt with no stage. The band is backed up against a brick wall in small area - acoustics aren't good. A band I've never heard of will come in and do a 1 hour, 1 set show. I usually provide all PA. My board is a Presonus 16.4.2 - I record all tracks to my laptop for mixing later. Most shows are standard rock band drums/keys/bass/guitars/vocals. For the last show I ended up with 20 tracks. 11 songs. The band did not ooze talent or great sound - but they did OK. My plan was to do a good-enough mix in about 5 hours - I probably ended up with 12 hours in the mixing and editing. So, assuming that the quality of my work meets their expectations, is it reasonable to spend 12 hours mixing a 20-track one hour show? One factor that will get better is that I've spent most of my time doing acoustic/bluegrass/choral stuff - so I'm having to learn the rock-band thing. I'd assume I'll get more efficient as I do more of this sort of work - but I'm still wondering what a fair price is for this sort of work.
