I've been hallucinating about installing a concrete pad of
about 1000 sq feet out the back. This would involve moving a
little bit of earth, but not a whole lot -- it's almost level,
and it's currently planted in grass. It would be intended to
accommodate a storage building and a patio, and it should be
able to be be driven on with an average size vehicle (say 4000
#). Clay soil, if that matters.

Would anyone care to take a wild guess at how much it would
cost me to buy this done?

Would anyone care to take a wild guess at how much it would
cost me and how difficult it would be for me to do it muself?
(Bearing in mind that I habe never done anything like this.)

Thanks!
look in yellow pages and see how much the concrete delivery sources
charge for a few yards of concrete now....
10 ft. by 1000 ft= 1000 sq. ft, by 6 inches thick=500 cu. ft.
1 cub. yard has 3X 3X 3= 27 cut. ft..
500 / 27 = 18.5 yds.. at how much a yard. and thats only for the truck
to pour the stuff if they can get to it by driving to the back and
pouring it... how many guys you gonna have helping you with wheel
barrows etc.. and shovels and bull nose trowels and what about wire mesh
for the concrete and the footings to hold the form down until the
concrete dries...... a whole lot of money after you find out what the
cost is per yard in your region.....
