322237 XML Feed real estate listings

I am looking for a programmer to create a PHP script to pull my listings from MySql database. Which will syndicate my real estate listings to sites such as Google Base, Trulia, Zillow, oodle, etc. The feed needs to be in an XML formatted text file describing our property listings, and providing a link to our website for more information. I would also like a cron job to be written to run this script on a daily basis.
