Lead Generation – Find & Verify Valid Email Addresses

I have a list of around 20,000 contacts with person name, job title, and company name. You need to find and add valid email addresses for each contact. Payment is ₹0.75 per successfully added valid email only; bounced, incorrect, or unverifiable emails will not be counted or paid...
