I had a similar situation at my old QTH - A3S at 35 feet, 2m boomer at 
43 feet.

Here's some alternatives. First, you don't necessarily have to use a 
ready-mix truck. You could consider mixing the concrete yourself. If 
you did this, you could rent a small mixer, and do two bags at a time. 
(Note that it would take in excess of 100 bags, so I wouldn't recommend 
this)

Second, you can rent a powered wheelbarrow to carry the concrete from 
the curb to the hole. either that, or get about four good friends with 
wheelbarrows to shuttle the concrete across the yard.

Third, if the hole is downhill from the road, you can rig up a trough 
to the hole. Failing that, you can rent a pump truck to move the 
concrete uphill.

At my old QTH, I have the A3S at 35 feet. Today it is on a tower next 
to the house at just under 50 feet. It certainly behaves differently, 
especially on 20m. Further, I have much less RFI in the house.

125 cubic feet of concrete seems like a huge hassle, but I've gotten 
much more enjoyment out of my station since I have a (modestly) 
improved station.
