I quitted my job and would like to focus on building my own startup. My idea is the following and I'd like to get some feedback on it.

IN ONE LINE: API to customise PDF templates with data

FULL SUMMARY: It's really hard and costy to build your own print customisation process(without the hassle of using PDF librairies) and especially for a small website unless you are ready to spend $120 000 (XMPie) to get an old style java/.net library to integrate it with XML message as a way to submit data. Why would you need that? Let say you manage a website for a designer. Each artwork is at the moment sold only once. Now the designer would like to take an already created artwork and use it for different customers. As an example, let's take a business card PDF. Customers visiting would be able to fill in an HTML form with name, address, title and phone number and get a PDF produce automatically with these information updated, without having any more integration work (for the designer). We provide: a web interface to configure and manage templates, a widget to add into your website to automatically create the form and an API to send directly the data if you don't want to use the snippet. Languages used to define the customisation config would be CSS and JS/JSON. Business cards, posters but also payrolls or any PDF related file could be easily produce or sold many times. Moreover, you pay by request.
