I am currently looking at the site. I am quite sure that I can do these scraper kind of work, only one thing I am bit worried about is because of dynamic nature of the website's structure; Usually scrapers some times stop working. In future if it stops working, i can try my best possible to fix it, but if that is out of my talent, i am afraid i can't do that. I believe it can be done but i can't guarantee. If someone does guarantee, I am sure that person is not right for you. I am willing to offer support for reasonable fixes (or rather you can call upgrades), but if it gets complex I might charge accordingly. Kindly reply me back so I can look into the site in more detail.
