LinkedIn Lead generation

I need a specialist to validate and update my list of London recruitment agencies. The task is as follows: 1. Validate all current emails—mark invalid ones. 2. For invalid contacts, replace with the correct decision-maker at the same agency (someone responsible for hiring). 3. Identify all recruitment agencies in London missing from my list and add them. 4. Ensure the final list is fully up-to-date, accurate, and includes all decision-makers at every active agency. 5. Do not touch contacts I’ve confirmed as correct. Deliverable: A clean, accurate, complete list of London recruitment agencies with valid decision-maker contacts. When applying, explain how you’ll validate emails, find missing agencies, and ensure the final list is accurate. Only apply if you have proven experience in lead generation and email validation.
