All India Doctors Database Excel format

There are many sites available. I need a database in excel format (one file preferably) of maximum number of doctors (while bidding you must commit to the number and i will select the bid with maximum number of doctors you committed). what i need is name of doctor(mandatory), specialization with degree, address, age, contact number, email(mandatory atleast 60%). accuracy is very very important. i will cross check the same before releasing the payment. for choosing the winning bid i need a small sample 100 doctors, which i will verify and choose the bid as winner. thank you for your time.
