Web crawler for two sites

We need a web crawler that will fetch data from two different websites (exact URLs in the attached specification document, we encourage you to at least browse it): - A university - An official book database (ISBN) And populates and already existing database. The program can be done in any reasonable language (Java, C#...). We have prepared a reasonably detailed specification documents that details the process and the existing database. We leave the GUI design up to the coder. The websites are in Spanish but our specification document (which we are posting here) is in English and it includes screenshots and translation of all relevant pages. When bidding - Please don't send us a huge list of links to other works. Focus on relevant stuff. If you've done 3 crawlers previously, just tell us about those. - When bidding, please mention what language you plan to use as well as any frameworks or libraries that doesn't come with the language. - Feel free to ask as many questions as needed.
