Just an update - I did end up taking my car to solo motorsports to get repaired. I have to say I'm extremely satisfied with the quality of work, how quick it was finished, and the price.
I was worried about various interior parts going back together OK, since replacing the battery cable seems like a lot would need to be disassembled. I'm pretty anal about that kind of stuff and there is no way you can tell anything was ever done.
I highly recommend these guys for any work needed in the Atlanta area and I wil surely use them again in the future for any repairs. But hopefully I won't have to.
