zappos.com or 6pm.com product feed

Hi, We have 2 proposal for you 1. we need a product feed in .sql, xml, csv...so on format from the [login to view URL] website, or 6pm.com. the feed must be updated regularly in order to have all the information (sizes, qty...so on) updated 2. we need the feed in the format that magento/magmi can import it in magento 1.7.0.2, or write your own extension in order to import and update products in magento Feel free to post, we will choose only programmers that have done that in the past. Thank you
