It's been four years since I flew into Dulles, so I called Signature (1-703-572-0001) for a fees update for a piston single. They're still extremely reasonable for an FBO at a major airport:
Ramp fee: $30 (waived with minimum 8 gal fuel purchase)
Landing: $10.04
Parking: $20.92/night
Customs: no fee
Staff estimated that a taxi into DC would cost $100, and a compact rental car is $45/day.
