Good detailing shop in DC area

Car looks like powdered sh*t from the consequences of this horrible weather. I want a full professional detail, like the ones the dealers do when they prepare a Certified Preowned car for sale. Carpets cleaned with hot water extraction, full interior cleaning with protectant, full exterior paint correction and cleaning with clay bar, etc. The works basically. I'm sure there are many options here I just don't know of any. Thanks
