ECN Forum Forums General Topics of the Trade General Discussion Area Running a buisness on the side, what is your experiences?

I am thinking of doing some industrial machine tool electrical, mechanical, plc, and programming on the side. Does anyone have any experiences that will give me some ideas on the do's and don'ts of running a buisness on the side. I have one project going now and have thought about putting my name in at some small machine shops in my area.
