Career Change...?

I'm thinking of a career change and what better area to look into than the health field. That's probably one of if not the only areas that won't ever stop needing people. The problem is that the colleges around here aren't close to me and even when I did try to get information packets I got the message that they weren't accepting from my area. How does that work?! So I've started looking for online courses and was surprised that I could do a medical assisting certification course online. I didn't think that you could. I'm going to look into it more but I think this may be the way to go if they can help place me after I were to graduate.
