Generate 500K USA & AU B2B Leads

I need a clean, 500,000-contact B2B database covering companies in every industry and every U.S. state and Australia. For each record I have three non-negotiables: a valid business email address (no catch-alls), a direct phone number, and the company name.

You may pull from any reliable source—LinkedIn Sales Navigator, ZoomInfo, Apollo, Crunchbase, public filings, etc.—as long as the data is accurate and compliant. Please validate emails (NeverBounce or similar) and confirm phone reachability to keep the bounce rate below 5 %.

Deliver the file in CSV or Excel, with clearly labeled columns for:

• First & last name (if available)
• Company name
• Business email
• Phone number
• State

I’ll review a 1–2 k-row sample first; once approved, continue in weekly batches, completing the full 500 k within four weeks.

When you respond, let me know:
• The tools you’ll use to source and verify data
• How you handle de-duplication and quality control
• Your timeline for the initial sample

Looking forward to a rock-solid list I can drop straight into our CRM.
