Basic data entry, compiling a list of Email Addresses - I have the source material

I have a website subscription that gives me a list of about 20,000 fashion brand websites. I need someone to click on the websites and find the email address, or quickly research and find them if they are not there. Some of the websites will have contact forms on them so there will be no email address. Am looking for speed and to get the list of 20000 as soon as possible. i will pay someone per 500 email address added and would expect someone to be able to add approx 200 every hour. Please bid per 500 email addresses added and I will give the successful worker recurring work on this project if the first 500 is delivered well. Immediate start tonight.
