Obtaining the email addresses of game developers

I have a list of names of game developers. I need someone to google each name, find out the business email address, and type it in the excel sheet. If the developer uses a web form as a means of contact, I need the website to be recorded as well. There are about 1200 developers. I have already done 400. So you will be searching the web for the remaining 800. I don't want any facebook or twitter website addresses. If there are several email addresses in the website, I want only the business contact. In short, there should be one email address for each game developer.
