When working for friends or friends of friends I have reluctantly accepted the idea that it is our responsibility to teach them what production costs.
It gives the musicians focus and purpose and you get better performances and a commitment to feedback during the post production.
It reveals the fact that almost everyone who says they don't have any money is using all their money on other stuff like sneakers and $9 beers. Eventually you get used to the idea that they will just as willingly spend money on if they are focused and committed.
I usually help friends by keeping track of the time at a fair rate and then demonstrate that I have written off some of the time if the friends or friends of friends remain focused and committed through out the process.
For me the pleasurable part is the overdub process and the final mixing while many bands assume that they will just jam out and you'll have fun recording them as they have all the fun.
If the band doesn't want to do overdubs to get the very best results then it is no fun for me, it is just work, and I charge accordingly.
I also have a firm policy that the multi tracks never get released for less than full rate. Period. I'm happy to multi track for people and let them take the tracks home to mix on their Pro Tools LE system. Full rate and you get access to all the hardware by the hour. It's a win, win.
I have found that a lot of bands that don't record often get burned out by the post process (the difficulties of which are inversely proportioned to their capabilities) and end up assuming they can grab the tracks and finish in their couch at home on their G3 tower. No problem. $.
Finally, if you speak to the band about this up front you can sense if they are focused and committed by their reaction to this proposal. Only a few out of every handful have the sense of purpose to do their best job. You can not force the ones that do not have a sense of purpose to work to your standards. You can save your self a lot of frustration by getting a sense for this as early as possible.
When you hook up with musician(s) that really do want to see stuff through to the finish then you can start negotiating per song or per project flat fees. I try to avoid that until I know that everyone is committed to having fun and seeing the project through to something you will be proud to have been part of.
