How much would it cost to build a 24x36x10 Pole Barn?

Question:I am looking to build a 24x36x10 Pole Building with a cement slab... I'm going to build it myself, but does anyone know what I'd be looking at for materials?

Metal Siding
Shingled Roof
Insulated

Don't have to worry about electrical or heating - got that covered. I'm in Michigan - thanks :-)

Answers:
look on e-bay for steel building, they're sold with or without ends and are very easy to install, that size without ends will take a weekend to assemble and should cost somewhere around $4000 plus appox 2.50 a foot for concrete
