Hi, I have worked doing webscrapping projects on websites like Amazon, Toysrus, Carrefour, El Corte Ingles...
I have a lot of experience developing this kind of systems.
Also not only in the server side, but also as an extension of Google Chrome.
Besides that I also have experience parsing PDF files, with or without forms, even designing and programming tools for Zonal Scan (OCR) on parts of a PDF.
The website you are indicating is made with PHPMaker, quite standard and easy to parse.
