Mongoose, just trying to be objective here, but also trying to save you some work. Why not just jack the sagging beams back into position, pouring a few properly-located concrete footings (at the 1/3-points) from which to do the lifting? You can rent heavy-duty jacks, or even buy a few off of Craigslist.
Or if you can afford it, the quick-and-easy way would be to hire an outfit that installs helical piers, using them to lift and hold the beams in their correct position.
