Sometimes it is best to back into the correct answer... The suppliers
are going to charge me for 5 yards of concrete in my area whether I
use it or not...
The other choice is to mix it myself.

It was about the same around here. I only wanted about a yard and where I
wanted it a truck could not get in very easy. Had 50 bags (90 lb bags)
delivered for around $ 300. Then rented a mixer for about $ 40. Spent
about 6 hours transporting the bags with my riding lawnmower and cart about
150 feet to the tower hole and mixing it up and then cleaning the mixer. I
did have water and electricity at the hole. Only put one bag in the mixer
at a time as that was all I thought I could handle by myself. Used 43 bags
in the tower and spent another part of a day putting the other bags in holes
and pipes for the guy wires. It would have been cheeper to just get a load
delivered and much faster, but just could not get a truck back there and I
just could not see wheelborrowing it to the hole .
