219315 PHP modification help

Hello, I have a one file that pulls affiliate data that I need a programmer to look at and edit- What I would like to have where it creates the title I can add the site name to the title and the ability to have the category name as a meta keyword and a metadescription. Also, once all this is completed the ability to have the links mod_rewrite htm SEO to be search engine friendly. Like I did state this is a one page PHP script that just needs some edits.
