What is the average cost for building a basic four wall concrete basement?

What is the average cost for building a basic four wall concrete basement? No windows most likely 9 ft ceilings unfinished.. Would like to sit a 2800 sq ft ranch home with stucco on the exterior of home. If you could give a rough price or average price per sq ft. Any help is well appreciated.|||all depends on the contractor... I would say dig a lot of it yourself (not that hard) but I would say easily $6,000 (Im in NJ, may vary by where you live)
