West Bengal Corporate Contacts Research

I need a clean, up-to-date Excel database that starts with two separate sections: first the practicing Company Secretaries who maintain an office anywhere in West Bengal, and then every company whose registered office is in the state—covering the whole spectrum from listed to unlisted, public to private. For every individual or company, capture these fields exactly: official website, LinkedIn profile URL, full office address, and a current phone number. Please keep names and spellings exactly as they appear in official sources. Suggested sources such as the ICSI member directory, MCA/ROC filings, SEBI disclosures, stock-exchange listings, and direct website or LinkedIn searches are all acceptable as long as the information is verifiable. Deliverables: • One Excel workbook with separate sheets (or clearly flagged columns) for “Practicing CS” and “Companies”. • Columns: Name, Category (CS / Company with type), Website, LinkedIn, Office Address, Phone, and the original source link for traceability. • No blank mandatory fields, no duplicates, and all hyperlinks must open correctly at the time of delivery. The project is complete once the file reaches an exhaustive, well-formatted state that meets the above criteria and can be filtered or sorted without errors.
