340571 Clone of a website

Hi , I am looking to build a freelance website that aggregate the job listings from 3 freelance websites .All these 3 freelance websites have rss/datafeeds .I have the web design ready but I need the php mysql script to do this . - Must use url rewriting and it must appear as html pages - I think the old job listings must be saved in the db for later access as the rss/data feeds shows only the recent listings Let me know Thanks
