I was self employed for five years many years ago.

It’s easy to find clients - one of the best ways I did it was to go to computer stores and tell the salespeople if they got me a new client I would pay them $15 per hour in perpetuity for every hour I charged the client. I had 3 people that made more from me than their regular job.

Then there are chambers of commerce, LinkedIn messages and frankly just putting yourself out there. I met my long term side client studying for a certification while my oldest son was at a baseball clinic. My client saw the book I was reading and walked up to me and said, “Are you in IT?”
