In most cases, I would rather do the work myself if I could get a permit. It depends upon your situation. If your service panel is in your garage it is almost trivial to accomplish an install. But it would all depend upon how handy you are, whether you know how to make sheetrock repairs, and understand simple electric circuits. (All those are good skills to acquire if you are a homeowner and have any time).
If not, a professional is a good bet but it might be tricky to get one in the area. Home Depot, ACE, or Lowes has all the required components even if you need plastic conduit. Also one can order the parts from Amazon including the wire. Again, I have done it for as inexpensive as $50 but it can also run up to $800-$1500 for a professional that does the full job correctly with electrical, sheetrock work, and paint.
Another possibility is that you could do the "rough in" work with a certified electrician checking your work if you pull the permit and discuss the project. Someone may know an electrician that would do that for a nominal fee.
