5175 contacts that I need emails for

I require a researcher to find email addresses for 5,175 contacts. I already have full names, company names and addresses; your task is to deliver accurate, verified emails with a high hit rate and document results in a clean Google Sheet. Verification methods and confidence scores should be provided. Reliability, attention to detail and experience in B2B email discovery and validation are essential. Future work may include generating targeted contact lists for GMASS campaigns, but please do not price that now.
