Create PDF Generator for Wordpress site

I would like to create a PDF generator (this can be done either by customizing the Woothemes PDF Generator which can be supplied or any other way) If you want to customize the Woothemes PDF Generator then this is what needs to be changed: Enable user to upload an image to be inserted into the PDF just like the text fields are inserted. The plugin connects the PDF to a store and makes you checkout even if the price is set to $0. I want the PDF to be downloaded instantly so there is no need to fill in payment details since the price will always be $0 . It is free so no checkout or shopping cart is required. I need the plugin to work without using Woocommerce (since it is slowing down the site). Right now the plugin is just an extension of Woocommerce and needs it to be installed to work. Once the shopping cart is disabled I assume that this can be done. Once they have filled out the form I want them to be able to download the PDF without having to go to a checkout. They should be able to print, save or email the PDF It is important that the code does not slow does my site. The plugin offers many more functions that I need and they are slowing the site down. I just need to use a small part of the plugin. [login to view URL] If you want to code without using the plugin this is what I will need: I need to upload an image which will be a template on which fields can be added (in the backend). In the backend I need to move the fields around so that I determine where about on the image the field will be placed. It will be different on each image. I need to be able to add text fields (which user will fill out on the front end) and an option to enable user to add image (via front end). I also need an option to add an image from a set of images that I will provide. I will then have a form on the front end which the user fills out. These fields will be inserted into the template that was created and they will appear in the PDF which will be created. On the front end - the user fills out the fields and sees a preview of the PDF which can then be either downloaded, printed or sent my email. It would be nice if the user could change the font, font size and color and also preview PDF before it is printed. Performance is very important and I need a solution that will be fast and will not slow down site. The site is a WP site so I would like to be able to easily insert this PDF generator into a wordpress page or post. I can send you an example of something very similar to what I want if you are interested.
