LOL. Doesn't work that way in the US. Unless you have wealthy parents, I suppose. :p
Nah, it can work that way, here, it's just that in our practice we're fairly well separated from those who do. Think of them as "micro-contractors." I knew a guy a long time ago who moved from place to place and worked offering himself as a handy-man or for construction where ever he went. I actually met him after he finished a six-month stint on a fishing boat.
Of course, there's a lot of business and union regulation in some areas which would prevent that. Stupid things like needing a low-voltage certification to run network cable.
