What can you do that takes you no time and is in demand? I figured out how to something that takes 4 hours in 15 minutes and charge flat rate for it based on the original 4 hours. There is a handful of annoying errors other techs make that I instantly fix without sharing my secrets. ;)
Context: I have first refusal rights in my territory as a field tech on another site. I bill $5000+/mo in gross receivables. It didn’t happen overnight. I started by doing a few unprofitable tasks.
