Collect ~350 Verified LinkedIn URLs

I have a list of roughly 350 emails or company domains that now needs one thing only: the correct LinkedIn profile URL. For each row you will search, confirm the profile really matches the email/domain, and paste the clean URL into a new column. If after a thorough check—advanced search operators, Sales Navigator tricks, scraping tools like Python-Selenium or Octoparse, and manual verification—you are convinced the profile does not exist, simply write “Not Found”. Please avoid placeholder or broken links; I will spot-check every record. Deliverable • A single CSV containing the original email/domain column and a second column with either the verified LinkedIn URL or “Not Found”. Accuracy matters more than speed, but this task should not drag on. Let me know your estimated turnaround and any clarification you need before starting.
