Affiliate shop website

The project is based on building a affiliate shop website. The real challenge is to import different xml feeds in a database, build up the database and clean it (duplicates,etc), and then export it to a nice shopping website. The webdesign is not part of this project, although the output must look userfriendly and has to be adjustable. i know there already are different scripts for example for joomla. we could also look at that kind of scrips for a possible solution, but the best way for me is that you make the xml import function the database matching and output to a php website. So: If you have experienc in xml feeds, databases and php it shouldn't be so hard to build. I have several projects like this so when we do one succesfully we could do more!
