Don,
We pay between $500 and $700 per pole base to our sub. But that is for smaller bases than you are talking about. The norm is 48" deep x 24" dia.
For that price our sub will drill the hole, fab the rebar cages, build the forms, place and finish the concrete.
All I have to do is provide one man to stub up the conduit runs and ensure the bolts are set properly when the concrete is poured.
I've done these without help in the past and it's not worth the trouble. I am not good at concrete........I'm good at running pipe and wire.
