custom web based scraper bot for real estate listings

I need a custom web based scraper bot for uk real estate listings. It must export the desired data to csv 1. url 2. address of property 3. Specifics 4. Description 5. Price I have attached two jpegs, one shows the main list of listings page (pic002) and the other shows a typical listings page (pic001), so for every new listing detected your bot should extract the data (maybe once per week) I am currently harvesting a list of uk real estate listings, this is expected to be in the thousands, but if you have done this sort of thing before than it should be easy for you to just mod the template per site.
