Scraping email addresses from a website

I require someone who is able to scrape approx 250,000 email addresses from a website and send the list of them to me in an excel spreadsheet. I don't care how you get them and you can have until the end of the month to complete, however I think that the winner of the project will have some kind of robot to do the job for them! Message me to let me know if you can do this and the time frame.
