leads: edu and jobs wanted

I am looking for leads going 30 days back best but legacy through 2011 are ok in the Edu, and Job niche. I will take bizopp leads as well, but prefer leads from job related domains. Also, I want a list that has been cleaned and only need the basic data (email, ip, timestamp, url. I am looking for as many as possible as long as they are quality leads. I would be happy to start with 1 million to test quality then if good buy remaining.
