Dig and pour a basement for a prefab in Kentucky?

I am looking at land in the Bowling Greene Kentucky area . I am interested in putting a manufactured home over a basement. My question is: How much to dig, pour, and possibly waterproof (want to use the space for home theater) a 10 ft wall basement under a say 28'x52' manufactured home. A guesstimate of total cost or a good rule of thumb per square foot cost would be very helpful for initial planning puposes.. Thanks!!!
