Collect 5K Emails & LinkedIns

I already have a lead list just shy of 5,000 rows that includes full names, company names, phone numbers, and—in most cases—the corporate website URL. What I am missing are accurate business-appropriate email addresses and LinkedIn URLs. I need you to enrich every row with both the personal profile and the company profile links on LinkedIn, then append the best-match email for each contact.

The finished file should come back to me as a single spreadsheet—Excel or Google Sheets is fine—with the new columns added alongside my existing data. I will spot-check for valid syntax, matching names, and live LinkedIn pages, so please run any necessary verification before delivery.
