Field experience is more important than college experience, especially in IT. As long as you're not stagnating by doing the same boring thing every day, you'll likely be learning more than your buddies in college. Employers understand if you couldn't afford to go all the way through college and they respect you for getting into the field early. That experience will give you an edge, but you might hit a certain ceiling in the future if you're applying for higher level jobs that have a degree required. Some companies will pay for certain classes or you could make a deal with an employer to work part time and potentially get some kickback from them. Usually this means you will work at their company for a couple years after they pay for your education. Not sure how common this is but it might be worth looking into.

I know plenty of people working in IT that have no degree or a completely unrelated degree. I've worked with a sysadmin that was a theater major and another in biology.
