Anyone know what I can expect to pay per sq/ft to have a concrete slab laid

[68Charger]

to put a 12 x 14 tuff shed on.

When I got a shed, it had a floor.. whole thing was delivered on a flatbed tilt trailer. Slab not required, just level ground- I put down a layer of crusher fines & compacted it to make sure it would be solid, but a slab would be overkill, unless they're going to build it on-site onto the slab...
