How much does it cost to straighten a slightly bent frame on a 1999 Ford Ranger?

I suspect a slightly bent frame on my 1999 ford ranger. It messes with the alignment ever so slightly, so that it pulls. How much does it cost (in southern Ohio) to straighten a slightly bent frame?

The best and most accurate answer will be the one a body shop appraiser gives you after inspecting the vehicle in person to see how bad the damage is and whether it can be done or not ( if the frame is in good enough condition or too rotten to try to straighten )
