Intercity Lines is who I've used several times. Figure on about $1.00 per mile. Never use those brokers who sit in their house, take a large deposit, and then just post your requirement on a public bulletin board for a driver to take.
I don't know what your vehicle is worth. Sorry the guy I recommended in Calvert didn't work out. Have you considered donating it? We donated our 1995 LandRover Discovery to Purple Heart. We got a tax write off for that. I don't know the value of your car. Just a suggestion. Love you, sha-Bop!
