I briefly worked with a house mover in Colorado a few years ago (1999+/-) on a Habitat project. If memory serves me well, he said that he was getting around $12 to $15 a S.F., plus materials, for raising a place and putting new foundation walls under it. Price could easily be around $20 or $25 a S.F. now, even more if it's a contractor who hasn't done much similar work. The Colorado guy had all of the jacks, timbers and lift beams, so he was well equipped and familiar with what it took. I remember him liking styrofoam-block forming systems for the walls he poured, being much faster and more efficient to work with than conventional formed and poured reinforced concrete.
Call a few contractors in your area for some firm pricing.
