Contract rates depend on location, duration, skill set, experience, and industry, and you've only given the first. So it's impossible to tell you what to charge (and I don't know the Utah market, assuming it's even uniform).

I recommend patio11's salary negotiation guide:

If you move from contracting to freelancing (which is a pretty big move), check out http://doubleyourfreelancingrate.com/

Very good material.
