Adding an Auto Proofing Overlay

I need to add an auto overlay for proofing of forms when we create them, for like a print shop.  After the Job is ready for proofing I would like to be able to send it over to PDF and it automaticly come out with a "signature line, Date, Company Name, and the image to be proofed"

If you have ever used a pdf proofer with an online site, want it to be like that.  I can have the overlay typed up then pdf it, just need to auto shrink my new artwork to fit in with the Temp file so it all comes out as one page.
