There are companies that do this. Like a lot of specialized construction 
things, you have to find them. I'd look for people who are in the 
business of planting utility poles. (and hope it's not right after a big 
storm, when those guys are busy fixing the downed infrastructure)

On the other hand, if you're looking at a big tower or an unusual soil 
type, then you should be talking to an Engineer, and they'd probably 
know the local vendors.  You should be talking to an Engineer to select 
the appropriate anchor type for your soil in any case.
