EPS, PDF and joboptions

Hi ! I've got a real nasty problem right on my desk here. The goal is to have a webpage where you can fill out adress/name/phonenumbers and regular stuff found on a businesscard. The user can also upload a .eps file together with the form. A preview in jpeg or png format will be produced. So far, no problem. But, if the user accepts the preview the data will be saved in a database. Later on a cron script will look for new data. It will then create a pdf and send to the printing company who will print the card and send it to the customor. However I have got a distiller joboptions file which according to the company contains all data needed to create a pdf of right size/quality etc. I have no trouble with the text and various fonts and so on, but, how should I include the .eps image? I came across a tool called ps2pdf and converted the .eps to a pdffile, but I cant get how I could include one pdf into another. Any help, ideas, thoughts would be appreciated. I will return to the list with some code if I solve this and there is interest of seeing it. Thanks in advance, Eric
