PDF generator for Wordpress/HTML

We would like to have developed a plugin/widget for Wordpress (and also to used in HTML, but Wordpress has priority) that can generate a customized PDF file from a base PDF file. It works with variables that customized by the generator. When the generated PDF file is ready it should be e-mailed to the person that is using it (also with a nice formatted HTML e-mail of course). The information filled-out should be e-mailed to a special e-mailaddress that we can provide in the plugin/widget. In the front end it shows that that PDF was generated and mailed already by this user (ribbon, checkmark, ,...), but the user can generate as much PDFs as they want. User details will be saved for recreation of the PDF. The plugin/widget should be flexible, so easily customized for other PDFs in the backend. The result in the front-end is a small thumb of the PDF with some info next to it. Then when one wants to customize they click the thumb or a link and they get a popup/modal window (like Speedo or Reveal) where they fill out the variables (some will be required, some will not be required). A nice button for create/generate and off it goes (text for the button should also be customizable, because we need the plugin/widget in different languages. For instance with a pricelist, the base price should be multiplied by a number to get the right price in the generated price list. Or they can upload a logo and their details to add these to the PDF file. It all depends on what the PDF can have! The plugin/widget should be flexible. We need to be able to create different PDF files with it (and place several on one page). The PDF file will have variables in the right formatting already in the document. In case of pictures there is a size that should be used. When the size is not correct, cropping and scaling should make it fit nicely. If possible extra modifications to logo's to fit it onto a product (like it has been printed with that logo) would be nice, but are not required for this version (later versions can add this). We need to be able to use different kind of multipliers in one PDF file, different kinds of textfields, picture containers and some other extra fields. In a future version we would like a possibility for the user to choose different PDFs that merge into one (with customization in each file of course). The PDF base files will be created in Adobe Illustrator. The variables can be inserted there in text (or if you have other ideas about this, please advise), dummy (transparent) pictures can also be inserted where necessary and then replaced by uploaded picture. Picture modification (scaling, skewing, rotation) is handy, but not necessary for the first version. Modification should not be done by the user, they only have to upload their picture. The PDF file will need to be saved with a password to restrict editing security and permissions settings. Other requirements: Compatible with WP 3.6 Major Browsers Friendly AJAX, jQuery, ... Files must be well documented, Code Notes, Inline description for functions and files Full code will be our full property after full payment. Developer should also be available for updates and upgrades (via Freelancer). Using PDFlib is not an option, FPDF, TCPDF or others, please advise! Please only bid when you can show similar projects.
