Fix googebase feeds oscommerce

Recently my google feeds, I currently have two started reporting errors, missing attributes and invalid character encoding. Because of these and other errors one feed is partialy live and the other is not. The feeds are identical except for the fact that one is for local listings and the other is international/global. I am looking for a programer who is experienced with working with feeds and can do this live. The store is modified oscommerce variation. I have alot of other simular work available once this project is done.
