The pay back then wasn't much. $17 cy, $30 lock, $30 toilet, $30 recut, $75 wint BUT gas was a lot cheaper and so was materials. what I loved was the simple time, no uploading, they had inspectors to report everything, we would just get a work order for what he reported, none of the responsibility of missing anything, just in and out, print an invoice once a month and mail it in.
We loved the work and made good money.
