Collections and input of (Business only) Email addresses

I am currently building a database of client connections in companies across the globe. I am requiring a skilled and intelligent person to get the BUSINESS email addresses of all the contacts i have on my database. This can be BUSINESS email addresses only. No personal email addresses will be accepted.

We currently have about 3000 contacts, and are still building the database - so there will be more.....

First name, last name and company will be given - Also country that the person is in.

Please let me know your pricing and skills
