Award points for Facebook Like - CakePHP

We have a site that is developed with cakePHP and we want to add a feature allowing users who like us to be awarded with so many points via mysql. So if a user is logged in and the hit the Like Button they will be awarded with 5 points. This will need to be created via the facebook API and Javascript. I need this completed today and all correspondence will be done via the website and I will not release any milestones until work is done on the test site. Once the job is complete I will release the 2nd half. So if you are a scammer and you cannot finish today then please do not bid.
