Hey, dadette.
If they can be towed (as opposed to needing a trailer) you might contact one of the auto auction houses in the Denver metro area. When I lived in CO I used to see them going up and down I-25 all the time, driving one car and towing sometimes two behind. Since they're not priceless and you're looking at them from the restoration standpoint then you probably know enough about the proper ways to tow them and that's probably a lot cheaper than trailer transport ... and this time of year, sufficiently safe.
I don't know if they have their own drivers or use various companies, but that's at least a place to start and probably the most economical.
Take care and enjoy the ride,
Greg
