Does anybody have any recommendations for good headhunters/job placement agencies?

I finished my degree four years ago but I have a physical disability and, due to my limitations, have not been able to find a job. I just wanted to see if anyone has any recommendations. Thanks!

EDIT: I have a law license and am trying to get into criminal defense or personal injury work. I am struggling because I am not able to speak loudly or clearly enough to be able to do the in-court litigation, so I am limited to the behind-the-scenes work (research, writing, trial prep, etc.).
