Turn an existing PHP fpdf utility into a codeigniter helper

I have a php utility that someone built for me that uses fpdf to create a PDF document. I need to incorporate that utility into a helper under my Codeigniter application so that I can utilize the utility to create PDF documents from my application. The utility works fine using direct access (you can see the results of a demo at [login to view URL],com/pdf/[login to view URL]). all of the utilized files are attached. Please review and make sure that you can incorporate this utility into my codeigniter before bidding. NOTE: The [login to view URL] file will be replace by my controller to build the output. It is basically the included php files, classes, etc. that need converted.
