MAGENTO 1.5: Products that generate printable PDF's

So I'll explain this as well as I can, please feel free to ask questions if I need to clarify anything.

• We create credentials from PDF's.
• The background image is already printed onto a piece of paper (A4: Landscape)
• From inputs in our products (Custom Options > Name and Date) and an incrementing credential number which is stored in our database; we overlay these on our A4 papers at specific coordinates to print a final product ourselves.

We typically sell around 400 ~ 900 of these a day, so we would need a combined PDF sheet that generates/adds all these to single printable document. How these are segregated from yesterdays orders or todays orders, or orders after printing todays orders doesn't matter. It could be by LAST credential number, or by date/time cut-off, or whatever. It's negligable as long as there is not duplicates.

Things I would like to see is the ability for the user to preview their credential prior to submission (JQuery would most likely fit the bill, I envisioned updating the preview image from the input fields), the ability to use a filter array or list (could be a flatfile?) so we can remove banned words, and lastly so we can correct mistakes even the the user makes them, a way to edit the PDF's, either direclty through a tool.

I've been looking around for a plugin or module for the last week that I could at least get a starting point on to do this. If not this is something that will need to be created from scratch. I looked at web to print by Zetaprints briefly but there is not only a complicated install process, but also a pay per use of about a $1.70 that would quickly eat into our profit margins.

What we do now This is the old version that we used with OSCommerce that will need to be replaced by a Magento equivalent.

Old Version with Edit Capabilities: http://pastebin.com/pafG0RLZ

New Version without Editing: http://pastebin.com/b4a3kim1

Here is the physical code of the new version that would need some kind of integration. Please stop downvoting me based on "theoretical concepts" since this is already a working product that needs integration.
