Can Consulting Company Keep Me from Job?

I am 4 months into a consulting job with the biggest employer of people in my position, probably in the entire down-state area. I found recently after talking to co-workers that I am getting paid half of what everyone else is getting. I am fine with working out the last two months of my six-month contract, but want to switch to a better consulting company (everyone seems to have a negative opinion of the one I am with now). However, in my contract there is a 1-year non-compete clause without permission. Can they keep me from getting reasonable pay at this employer? Is there a way out of this? Would it be possible to quit before my contract? Thank you!

Just to clarify I want to add the actual language of the contract. I also want to point out that the actual company is probably the largest employer of my position in the down-state area. Wouldn't this contract be too restrictive and force me to work for this consulting company at whatever wage they determine?
