cost to add a 20 x 30 room on to my house

How do I figure the cost to add a 20 ft x 30 foot addition on to the back of my house. i will have a contractor build the foundation, outside walls, windows provided by me, siding, and roofing. All interior work will be done by me later. I just need to know how much to expect a contractor to charge to build the shell and finish the exterior.
