No doubt anyone with demolition, renovation, or building skills (or, even better, their own equipment) can make lots of money... and do quite a service in an area where there's undoubtedly years worth of work left to do and a finite number of people available to do it.
Honestly, I suspect there are job openings in all sorts of fields, either already or coming soon, as the area rebuilds itself. marrus really made me think by asking me if I could see myself living there. I think the answer is... maybe. :-) Aside from being certain that I would hate the weather every summer (not even counting the hurricanes), I'm not sure if I know enough about the area to feel that I'd be comfortable living there as opposed to just visiting. (I know I love visiting.)
