1949 Willy's pickup repairs in Virginia

I am a new owner of an antique Willy's pickup (and very excited). I live in Arlington Virginia and have just purchased a 1949 Willy's pickup (4WD) with almost all original parts. Needs work on differential seals, transfer case leak and new gas tank. I am ordering parts, but I expect to need some assistance for awhile in the repair work. Can anyone recommend a SOLID repair shop in the northern virginia area for this vintage vehicle that can be my go-to location for the future? Many thanks.
