Upload Of Product Price Addon For Ultimate Version

Hi I'm looking for an addon/script that could do the following trick

I need a this in order to run our multiple store front prices.
Product only exist in the main store.
It should update the prices of the products directly in the SQL tables, based on a file that we would drop on the FTP server as all the rest is shared.
Please mind the cache as well for the price. If I remember correctly I’ve read somewhere that it was mandatory to flush the cache for the price after doing this.
Thanks !
