Granite fitting contractor

Sumit Enterprises finalizing the contractor for laying flooring, kitchen otta, door frame, window sill etc. The work will be done for a new house so no cutting or demolition work is involved. My challenge is that I am out of country and trying to manage this remotely. I spoke to a contractor and my gut feel says that the rates quoted by him are very high. I would appreciate if members can provide their inputs/comments and share their experiences on the current market rates for the same work. I have mentioned the rates mentioned by the contractor below. We can add more items so that all members can refer and know the current market rates.
