Blasting bedrock for a driveway

Hi,

I am looking at some land to buy but it has one big problem.
A driveway needs to be put in place thru long and high bedrock.
I was wondering if anyone would know a approximate cost from my explanation.
I know these approximates can be way off but I'm just wondering if it is worth the hassle.
I am very curious about this and may try and get a quote from a contractor.

Basically the bedrock is 50ft high from the road to the level part of the land.
The drive way needs to be about 20 ft wide and I believe the driveway will be 500ft long.
The driveway needs two and half switch backs.

I am told that this rock needs to be blasted.

any info would be very much appreciated

thank you
