219527 PHP script modification

I have a well-designed, code-igniter based php script perfectly installed and working here: [login to view URL] The web is in Spanish, but it is just a place where you can submit your complain about whatever you want. I want to modify the script so: 1.- In the home page, 1-1.- There is a link inside each complain, pointing to a page dedicated to it, like this: [login to view URL] 1-2.- When a category is clicked like "Reciente", "Trabajo", "Estudios", etcétera, the title meta tag for the page has to change to the title for that category available in the "Categories" table that will be available in the database. This field is not yet available in the database, so it has to be added. The same for the description meta tag 1-3.- Pagination must be improved, introducing one similar to digg 1-4.- Instead of an star-based vote mechanism, we will just have a "vote" link, so you can only vote for a complain, but without specifying number of stars that you give to it. 1-5.- Make it possible to add a complain by submitting it to a certain twitter username. 2.- In [login to view URL] 2-1.- Make it possible for users to submit their comments to that particular complain from the form that appears at the bottom of the page These are simple and quick modifications, so please bid accordingly. Thanks
