Banquet/Hotel Decision-Maker Lead Sourcing

I need a fresh, accurate list of 500–1,000 decision-makers who can influence or purchase luxury lighting solutions. My primary focus is banquet halls, but high-end hotels, builders, architects, and interior designers in India are welcome additions. Key roles include General Managers, Procurement, Facility and Engineering Managers, Banquet Managers, Architects, Interior Designers, and Developers.

Geography is fixed: Delhi, Mumbai, Jaipur, Lucknow, Varanasi, Bangalore, Hyderabad, Kolkata, Ahmedabad, Pune, Udaipur and major cities of North India. Within these cities I would like you to prioritise Taj, Oberoi, ITC, and similar premium chains or standalone venues that match their calibre.

The final output must be a Google Sheet containing for each contact:
• Full name and job title
• Company name, city, website, and main phone
• Direct email and phone whenever you can verify them
• LinkedIn profile link
• Source URL or note so I can trace every entry
• And more information which help me contact that person

Use LinkedIn Sales Navigator, corporate sites, reputable hotel or architecture directories, and Google searches—whatever reliable tools you prefer—as long as you double-check accuracy.

Acceptance criteria
• Minimum 95 % of contacts must have working LinkedIn URLs
• No more than 5 % bounces on delivered emails (I will spot-check with Hunter or NeverBounce)
• Duplicates across chains or cities will be rejected

When you respond, include a concise yet detailed project proposal: outline your research workflow, any enrichment or verification tools you rely on, and the timeframe you need to hit the volume target.
