Check 1182 websites

Hi, I have an excel-file with 1182 different websites. I need someone to check each one of them to see if the websites are still active. It's blogs, so some of the sites will we redirected somewhere else is they aren't active. Is this something you can do? How long will this take? The excel-file can we downloaded here: [login to view URL] The ones that are active sould be denoted with a 1, and the one that's not active should be denoted by a 0.
