National Corporate Database for Gifting Campaign

I’m preparing a Navratri-Diwali corporate-gifting campaign and I need a fresh, accurate list of decision-makers I can reach out to. Please help me build a National-level database of top 1000 medium-sized companies and funded start-ups operating in Technology, Retail, Healthcare, Finance, quickcom and Fintech. The companies should be based in India. The people I must reach are HR Managers or Sourcing Team Leads—the ones who typically approve or shortlist gifting vendors. For every contact, I need: • company name and website • city and state within India • industry sector (one of the five above) • contact person’s full name, designation, verified corporate email ID and direct phone / mobile number I will use the list for a targeted email-plus-call sequence, so bounce-free emails and active numbers are essential. Please share a quick note on your data sources and any verification tools you rely on (Hunter, Skrapp, ZoomInfo, LinkedIn Sales Navigator, etc.) so I know what to expect in terms of accuracy. Deliver the final file in Excel or Google Sheets, clearly labeled and ready to filter. Let me know your estimated record count and timeline when you bid - speed is welcome, but quality matters more. Also, the bidders should be based from India only.
