Zend specialist for small adjustment

I have a script that uses Zend and right now when one of my users clicks on a twitter or facebook link on my website it simply tracks an incremental number. Instead, I'd like to associate each click with a user in the database. The result should be that I will know which of my users has actually clicked on either a twitter or a facebook icon on my website. Looking for someone that can start and finish the changes right away.
