Sadarahalli rate / vendor@sarjapur/mar'halli recommendation

[ngupta]

I found different people quoting differnt rates for sadarhalli stone;
On outerring road marthahalli ppl are quoting as high as 60 psft;

What is reasonable rate for it?

any good vendor to deal with around sarjapur/marathahalli/banaswadi area;


also how they charge for transportation/loading/unloading, though 'm aware everything is negotiable;
