What I'd suggest is using a pdf form. Create one where everything is already set except for your 3 or 4 dynamic fields. In perl create a related xfdf file (xfdf is a lot easier than fdf since it is an xml based file). Then make a system call to pdftk (http://www.pdflabs.com/tools/pdftk-the-pdf-toolkit/) to merge the data into the form and output the pdf with your dynamic data.
