Yeah, retaining an attorney from the get-go was a very, very bad idea... how much will it cost you to drop him?

There are a few things you should have determined, first:
1. Resolving a collision outside of insurance only works for small fender benders. You need to call and work with your insurance.
2. Does the guy who hit you have insurance? Then his insurance will pay all your costs, including medical, up to the limits he is insured for. But let your insurance deal with his insurance. So call your insurance agent. And let any doctors you go to know that your injury is related to a car collision. This changes the way they bill you.
3. Do you have uninsured/underinsured motorist coverage? Then YOUR insurance will cover shortfalls and go after the other guy for reimbursement.
4. If the other guy has no, or not enough, insurance and you do not have enough insurance, THEN you hire an attorney. But as Petrolio said, only the attorney will be happy in the end of that scenario.
