300k US Executive Email Leads

I need 300,000 fresh, valid email contacts for U.S.–based executives delivered in a single batch within 24 hours. Every record must come straight from ZoomInfo, PitchBook or LinkedIn and cover only the job titles below:

• Project Manager
• Project Accountant
• CFO, CEO, COO
• Accounting Director, Controller, Accounting Supervisor, Accounting Manager
• Chief Accounting Officer
• Accounts Receivable Lead
• Escrow Officer

Basic verification is enough—just ensure the address is syntactically correct, not a catch-all, and passes a quick bounce check.

Deliver the final list as either a CSV or Excel file, clearly labeled and free of duplicates. A quick preview sample (1,000 rows) midway through the job will help me confirm we’re on track; the remaining 299,000 should immediately follow once approved.
