So then how do you schedule them if they don't compete? Is this more of a "fill your spare capacity" setup or do they work certain shifts? Also, what is your average response time? Same day or scheduled in advance? I don't really mean to reveal all your secret sauce, but since I dealt with this stuff for a couple months I'm curious. The mechanic I worked with wanted to go big time but my partner and I decided he wasn't a good fit to run an operation at that scale.
