Build a contact list using LinkedIn

The project was about Lead Generation. I'd generated for Company size, Industry, Location, Name, Title, Email. 

 I've used Linkedin, data.com, rappotive gmail, mailtester & son on to find the valid contacts.  
The deadline was 7 days. But I completed the task within only 1 day. My client is totally satisfied with me & have hired me again.
