500k Contact Email Scrape

I need a clean, well-structured database containing 500,000 B2B contacts who hold IT or other technical positions. For every record, capture the email address, job title and company name so I can plug the list straight into my outreach workflows. My priority is accuracy and deliverability, so I expect your process to include reliable scraping methods, thorough email verification and de-duplication before delivery. I have not fixed the industries rigidly—my brief simply says “databate”, which means I am open as long as the people you pull are genuine IT & technical staff working for real companies. Please deliver the final file as a CSV (or Excel if you prefer) with separate columns for: • Company name • Job title • Verified email address If you already have parts of this volume on hand, let me know how fresh the data is; otherwise outline your collection timeline and your verification stack (Hunter, NeverBounce, ZeroBounce, etc.) so I can see the path to a high-quality, bounce-free list. I’ll review random samples on receipt and run a quick deliverability check—records that fail the test will have to be replaced. Let me know your estimated turnaround time and any milestone strategy you propose for batches before we move to the full half-million.
