How much would It cost to build Nuketown for Airsoft/Paintball?

My father and I have realized that in our town and the surrounding area there aren't many things for teenagers to do, In fact the ONLY things to do around here are drugs.. So we've come up with the idea of an airsoft/paintball field. We wanted to actually build Nuketown from the game Call of Duty Black Ops.

I was wondering how much you believe this would cost, Money isn't a problem for us as we have many sponsors, investors, and charities wanting to work with us on this idea. The houses do not have to be functional, they just have to be safe to run around in. If you want to know what Nuketown is just Google Nuketown and i'm sure there will be many pictures of it.

If you cannot find a picture, We would need to build a cul-de-sac with three non functioning houses including a bus and a semi truck and trailer (they don't have to function either.) We would need a 6 foot fence surrounding it, a 30x30 warehouse type building that leads into the field for the business to run out of, (a 10 foot ceiling on the building would be fine) and of course black top and cement.

Thanks for your time and I hope to see your answers below.
