Does this question only cover products? I was doing side work for two companies, and I quit my job of 8 1/2 years to go full-time independent, doing automation and sysadmin stuff for them, have a couple more customers coming on too. Gave myself a HUGE increase _after_ taxes and insurance. To clarify, I have signed contracts that are committing to certain lengths of time. It's not something that I would have quit my day job for, without a significant part of the risks mitigated.
