Lead Enrichment (PERSONAL Phone & Email)

I build target lists and I need verified direct personal contact info for the leads. Mainstream databases and consumer lookup tools miss or return stale data on a meaningful share of these people. Closing that gap is the job. What you get from me: - A list of named individuals with organization, title, city, and LinkedIn URL where I have it - The work emails and main lines I already hold, so you only fill the holes What I need back per contact: - A direct phone (mobile or direct desk line, NOT the main switchboard) - A verified direct email (confirmed, not a guessed name pattern) - A short source and confidence note on each data point Scope: first batch is about 300+ contacts. If the first run comes back clean, this could become a regular batch. Method is yours to choose. I'm buying accuracy, not a particular tool. Bounced emails and dead numbers are exactly what I'm paying to eliminate, so verify before you deliver. Put in your proposal: - The sources and tools you use, and how you verify a record before sending it - Your typical bounce and accuracy rate, and how you handle misses - Turnaround on a 300 contact batch - Rate, per record or hourly Deliver as a CSV or Google Sheet in the column format I provide.
