you'll need a truck with a low boy or a hotshot. I know of none in those areas, but I would search for hotshot or freight companies in DC area and contact them for advice. Or locate one in colorado and have them coordinate the load. a hotshot truck will be most expensive but fastest way. A regular freight might be cheaper but slower.
Don't take the first offer, shop around a little unless you are in a big hurry.
What kinda lift ya moving? warehouse type or telescoping boom type?
try contacting some of the trucking companies from colorado. if they drop off a load in the d.c. area, then they would like a load back to colorado instead of "dead headin". they will give you a cheaper rate to get their truck home. i.e. a "back haul rate"
