There was an article on this very topic a couple of weeks ago in my local paper. What careers are good choices for people who don't want college degrees? I can't post it, but here are a couple of articles on the topic. In most cases, you can do without a college degree, but need at least some sort of technical schooling. Off the top of my head, I know there is a 2 year college near me with a 2 year program for some sort of radiology tech training. The pay starts in the mid-$50ks...and there is now a 2+ wait list for the program.

Once you know what field you are interested in, you can go here, and see what the pay scale is like for certain areas:

Sometimes you have to take a lower-paying job if it's at a company with a lot of potential for growth. If there's a good chance you will get good promotions and raises rapidly (and by rapidly, I mean within 1-3 years), it might be a good opportunity for the long haul.
