I have an experience for generating leads for US companies, I can share some of my work with you. I can help to extract information like linkedin link, person name, company, website, no of employees, year, email, phone, title, previous company, university, facebook links & linkes, twitter links & likes.
To speed up the process, I have few tools that I use to get some details automatically. I change per row basis. May be we can discuss more on chat.
