30K Oil & Investment Contacts

I need a verified database of 30,000 companies operating in the oil & gas, investment, and manufacturing sectors across the UAE, Singapore, Hong Kong, and India. The file must include two reliable contact channels for each company: a working email address and a direct phone number. Accuracy is critical—bounce-free emails, current numbers, no duplicates, and correct country assignment. Sources, scraping tools, or platforms you prefer are fine as long as the data stands up to random spot-checks. Deliverables • CSV or Excel file containing: Company Name, Sector, Country/City, Email, Phone. • A brief note on the collection method and any verification steps taken. Completion is confirmed once a random 5% sample shows less than 5% invalid contacts.
