Introduce University Student Friends To Join Social Networking Site

I am running a social networking site and I need sign-ups. Please recommend your university friends. This is how I am going to authenticate if the friends are real and introduced by you. Upon signing up at my site, send an email to your friend using your university's domain portion for its email address, for example, AT [login to view URL] , and to my official email address as well. If that friend of yours receiving this email from his university email address (ie. , say, AT [login to view URL]), replies back to everyone that he agrees to sign up, then this is proof that the email he sent his consent is derived from that OFFICIAL university's officially given student email address, and secondly, that he or she has given his in-principle consent. Let me know if you can do this. Let's begin off with 500 university student friends of yours, and then we can proceed from there. You must be comfortable with the above arrangement.I will also personally email to some of these people and chat up with them in email to further authenticate they are real. And I will pick these people at random from the list of 500 university students. Lastly, the fact that I am putting up these job for data-entry jobs, programming job and web promotion job is obviously for students in these fields to introduce to their friends. No confusion from here, please. (Note: if your offer is on SEO promotion, or introducing visitors to my site, please don't bid, as I am only interested in genuine sign-ups from GENUINE university students.)
