Create crawler / spider to gather information form website, and be able to update manually every time i want

I need the underlying information from the subsites following webppages: [login to view URL] [login to view URL] [login to view URL] I need the names of the contact plus the above information (if provided) for all the contacts under the upper three links. And I want to be able to check it out periodically to be able to keep the information up to date. See attached document for more information. Perhaps the following link helps for an easier way to collect/crawl thise data? [login to view URL] Would like to discuss the options.
