How much does a computer teacher make a year?

I have friends that are technicians, and from what they've been saying they make anywhere from 15-25$ an hour working for someone. Fairly rough estimate I guess, but it might help a little bit. It depends a lot on where you work, or if you work solo. With 0 experience and no certs, I started at $12/hr, and within a year got bumped 25% to $15/hr. Health paid, too.
