Javascript Star Rating System for Business Catalyst that can restrict with both cookies and IP Address

We have an existing site that is utilizing a [login to view URL] star rating system to allow visitors to rate user submitted photos and videos on the site. You can view the photo gallery here: [login to view URL] note the star rating on each photo entry what displays the rating as well as number of votes placed The client wishes to urgently swap this service because it has come to light that the Polldddy's rating system controls multiple voting restriction by only using cookies and we are having some users that are simply turning off their cookies so they can over inflate the popularity of their photos/videos. Therefore we are looking for a javascript professional to write a more reliable star rating system in Javascript (ideally based on jquery) that will restrict voting using both cookies and IP ADDRESSING. This additional IP protocol is to ensure users cannot circumvent the one vote only rule. The new system would need to provide a similar visual output to the current one. There is some significant urgency on this project, so please submit your proposals outlining your experience and realistic timelines for delivery of a working/installed script. Thanks, I look forward to your proposals
