Though I posted this almost a month ago, I wanted to respond to the great comments. They reinforced what I've sort of half decided.

I'm not a builder, I'm okay with my hands, but I don't think I would hold up under that kind of workload (along with my current 9-5) I could potentially save a bunch of money, but it would probably be smarter to spend the time and get some freelance design jobs or some smallish web-programming things to make extra money.

I think the main thing that turned me off to building is the responsibilty. Like Spliff said, if the roofer doesn't show up, its nothing to them, but its up to me to figure out what to do. The other thing, is if someone gets hurt (especially say my wife or another family member) I'm responsible for that.

So, I guess no GC for me. Probably better that way. Thanks for the comments.
