I can clearly remember plenty of $1,000 bucks gross days working for a big property management outfit. Their customer base was condo apartments 2 story to 30 story. Most are located in the same general area of the city. I charged $50 bucks for each service call (service charge) and my full labor rate, one hour minimum, except I finished most of the jobs in much less than an hour. I would hit the first one, drive 2 blocks over to the next one, 3 blocks to the next, you get the Idea. I tried to do all their stuff on Friday's and Saturdays. The bills went directly to each condo association board, so nobody wised up about how much this was making me. That gig ended when the woman who called my company all the time quit and her new replacement's boyfriend is one of my competetors.
