I don't get it.
About the plumbing thing, you probably paid a plumbing company 40.00 an hour, and the plumber got 20-25 of that. Probably less. My boss charges 65.00 an hour and most of us get 20 or so. When you work on the side is when you make the cash. I've made 1000.00 cash in 8 hours on a Saturday many times. Problem is you can't do that Monday through Friday!!!
