Employees mapping in a company- Deep Internet research and calling

Hi, I am a Recruitment Consultant at Bangalore. As part of an assignment, I will need employee / Talent mapping of 5 companies in India for Sales Dept. I will provide the format to capture the information. Details needed will be Number of employees in the sales dept, each of their Names, Designation, Compensation, mobile number and email id. The report needs to be fairly accurate ( over 90% ). The job will need deep internet research skills, Web scraping, research on LinkedIn etc and needs calling them when needed ( compensation, Company sales structure etc data cannot be relied on Internet info ). I would prefer someone from India ( helps in calling ) and who has exp in Internet research to make a report. I will provide the pitch info for calling and other info for mapping, to help get started.
