Create an automated product datafeed from my site

I have an volusion webstore and need some sort of system which will run through my site on a daily basis and pull all the results into a CSV feed and save this in a specific location on my FTP. This product feed will be used for my Google shopping site and be used for a number of affiliated shop comparison sites. Some of the details I would need in my feed are: Product Name Product Code Product Category Product Description Product Price Product URL location Product Image URL
