Check out Myler disability. That's who I used. You don't have to pay anything unless they win your case and they stay on top of everything. The day I would get denied, they would appeal it. It only took me 5 months and I barely had any medical proof. If they do win your case, they only get a portion of your back pay, which is how much money you would have gotten if you got accepted from the day you applied. I got like 4,500 and they took like 1,200. So to me, it was free.
