I'm trying to set up a gig where I can prepare multiple audio tracks for shows, and create playback show files if needed. A show will vary from about ten straight forward playback tracks up to around thirty tracks that are edited for time and content. Some tracks may need work to clean them up where others don't. With something that can vary so drastically, there needs to be the option not not set a price until after a discussion with the client. As it is, it's impossible to set a price, as you'd be over-pricing the smaller gigs or undercharging for the huge ones.
