Good shop in D.C.?

Hi, a very close friend of mine needs to have an AVIC-N2 and a direct-link changer installed in her husband's Expedition Eddie Bauer, and since I can not work the trip and the install into my schedule for this month, I would love to hear from someone who personally knows of a good custom shop in or around the 20003 Zip Code.  The installation needs to be perfect, and I am thinking that she will not be replacing the speakers or adding an aftermarket amp and sub anytime soon, so they will have to know all about Ford Premium systems.  If they are capable of hardwiring an RCA to the factory sub amp's signal input from the AVIC's Sub out it would be a plus.  Thanks a lot!!

hey, I think you called me! i'm from jkl Aftermarket in silver spring. Hit me up man we'll take care of it
