161679 PHP API Integration - Zillow

I run my dad's website, NorthGAMountainTeam.com. I want to provide this site with Zillow integration. Zillow is a website (see [login to view URL]) that allows you to search for homes and do various things (display maps of the area, estimated home value, pics of homes for sale, etc). It is basically a real estate search tool. Zillow provides a public API so that real estate professionals can integrate Zillow functionality into their site (Zillow API site: [login to view URL]). A help forum with code examples of how it works is located at http://www.zillowapi.com. What I would like is a well-written PHP Class that interfaces with the Zillow API. The portion of the code that makes calls to Zillow should be modular so that if the API changes in the future, we won't run into problems. Design is not included here, all you have to provide is a basic HTML page with a demo of each tool working (and a modular design). The design and actual integration will likely be another project. I have PHP 4.3.11 and PHP 5.1.4 available. Thanks for looking!
