I need to drill many (50 to 100) 1 1/2" diameter holes 6" deep in
solid rock for steel T-posts for a fence and I haven't decided how to
go about it.

What type of bit/drill combination would be most cost effective?
Electric drill (size?) with core bit?
Pneumatic drill with impact bit?
Other combo?

The location is far from power so the job would require a portable
generator or a compressor if a pneumatic drill was used.

I have a 2hp 20 gallon compressor - would be sufficient to run a
pneumatic drill to drill the 1 1/2" holes?

Rent a core drill?

As suggested, it MIGHT be cheaper to have someone do it. It WOULD be a
whole lot easier. You might be opening a bag of snakes.
