Extensive Zillow.Com Scraper

For this project you will need to have extensive knowledge of [login to view URL] and how to scrape data from their maps. The Application will first ask the user for a: - ZipCode/Address - Radius - Minimum price What the application needs to do is retrieve ALL of the Zestimates FOR ALL of the homes in that radius from the zip/address. When I say "ALL" homes I mean, homes that are on sale, that were sale, that were never for sale. EVERY single home that is on the site in that area should be put in the database. I have most of this code already since I have an application just like this but scrapes only the for sale and recently sold homes. The only difference is I need EVERY home in the radius. I have this code in both PHP and C#. We expect you to be able to extract most of the data on the page, including but not limited to, Zestimate, Address, Price history, beds/baths, etc.. Lastly, you should display all of the results in a nice clean interface. I should also be able to filter and sort the results on this interface. I should also be able to save the search for viewing later, and so obviously I need a way to load a previously saved search. Please let me know which technology (C++, C#, PHP) you will be using to create this app and what database you will use (Access, Excel, MySQL) in your bid Please note we WILL NOT be creating a milestone for the project until a certain amount of work is shown to us. And there will be a strict deadline for the project, in which if you are late you will be deducted a fee from your payment. Thanks
