pdf-publishing from template

I'm in need of a pdf tool for use in automated invoice-generation-and-email module. _Requirements_ Create pdf document based on a design template. Look at the attached file. The anticipated PDF-script or PDF-sub-system, takes input of data or data-references-to-database and another input of a design-template reference. The said anticipated PDF-script outputs the required pdf-document based on design-template. Do let me know if this is something that you can help us achieve. Changes: Find the referred pdf file attached as "[login to view URL]".
