Reputable/recommended install shops in the DMV area?

Greetings all, New owner of a 2019 Civic LX Sedan FC2. Looking to do some exterior/interior mods and not a DIYer. Dealer has agreed to give me 10% of factory install parts, but looking to save money on doing aftermarket parts. Any recommended shops if the DC metro area? Sorry if this has been asked before, but couldn't find this question in the forums. Thanks!

I heard some good advise on the Baltimore WCBM 680AM radio show "You Auto Know" (listen online). Look for shops that provide Jasper engine replacements and/or BG fluid services (preferably both) as neither of these companies will sponsor their name with a second rate shop.
