Add some features to our webesite

FavSync is a bookmarks manager. Bookmarks on FavSync are stored inside tabs and categories. One of the features we have is PUBLIC TAB. It allows the user to create a tab which will be publicly accessed (regular tabs cannot be accessed by anyone except the owner of the tab). It is already working (you can see how it works by going to our website: [login to view URL], creating a new tab, open settings and change to Public). We would like to add the following functionality to the PUBLIC TAB: 1. Possibility to rate every bookmark 2. Possibility to rate a public tab 3. Possibility to link someone else’s public tab to your own FavSync account, so it will appear like one of your tabs. 4. An external page that will show all the public tabs of all users and possibility to search and sort in that list. We will provide the PSD file. Our code is PHP CodeIgniter framework and we are working with SVN and Skype. You will have to sign a NDA contract. We’re not interested to see your previous projects, we ARE interested in some code samples of a model, a view and a controller, preferably that are connected to each other, not just random files (but if you don’t have, then send us whatever you got). Our head developer can help with any question regarding the existing code.
