Paying for a letter takes 1/2 day? Costs $600???? Someone is making money on you. My lawyer,(representative) who saw me though my hearing etc. didn't collect until my case was settled. The main thing that helped me was a" private", written letter by my primary care Physician. He said in just a few paragraphs what was needed to tell those hearing the case just what was wrong. He dictated it to his nurse and never charged one thin dime. The letter was brought up in court, and the judge granted my SSD on the spot. Perhaps your PCP would do this for you. In this day and age with PC's and fast printing, I can't see what the $600 is for. I think they may know how important these letters are and are taking full advantage. This is just my opinion, and what happened to me. I hope things work out for you. ginnie
