Depends on the size of the pump. A starting point around here is about $500 and could go as high as $1000. The pump is usually charged by the hour from when they leave their shop.

FFS man! 6" with rebar and 4000 PSI mix is so overkill it is not even funny. 6" with 4000 PSI mix is essentially a heavy commercial driveway,

That's what I have in my shop floor to hold all of those big vault doors.

That’s what we used for the apron outside the barn. Inside, where we thought we might be running a hoist and working on tractors, we went 8”. It is cheap insurance to go a little thicker and only costs the concrete. The finishing is the same. When you are pumping (wheelbarrowing over the rebar and pulling up onto dobies as you go might get a bit tedious), not that much difference. The apron we were able to tailgate, but no go in the barn.

Pumps are for sissies

We built 3 grocery stores for the same guy, and the last one had a full basement. We pored the 60' x 160' suspended slab with plain ol' wheelbarrows. (Not all in one day) But that was in 1974 and unskilled labor could be had for ~2 buck an hour, leaving the skilled guys where needed.

Would not do it now!
