Build an exhaustive list of all hospitals in select Indian, & other details including, email/ telephone contact of the head of the procurement divisio

We require an exhaustive list of all hospitals in select Indian cities (with a priority to hospitals with 50+ inpatient beds, clinics and diagnostic centers are less important unless they are established chains.) (Government hospitals and teaching hospitals to feature in separate lists.) Other details to be recorded are name and email (or telephone) of the head of procurement (CEO/ CFO for smaller hospitals) for the hospital or chain of hospitals. We are primarily interested in the email addresses of the head of the procurement team. Telephone number and address of the hospital, other important email addresses. Number of beds in the hospital. This study will include 5 Indian cities, starting with New Delhi (Gurgaon and Noida included) and then to move onto other cities (eg. Mumbai, Bangalore, Hyderabad, Chennai and Kolkata) if the quality of work is worthy. Information gathered can be through an online search or telephonic conversation with the hospital concerned. High quality data is of utmost importance.
