ha, that was my favorite excerpt as well!
My father full time contracted for a while in the GIV. I remember him making alot of money doing it. Although I remember him feeling like he couldn't say no and he personally didn't like the non guaranteed income. But your right, your working for yourself and you control the schedule...it can be a little scary, but I personally think it's the way to go. I know a few others that do it very successfully as well, It can really pay if you build a good name for yourself.
