Price comparison script, clone of kaonsoftwares

I need a price comparison script, best would be a clone from this one [login to view URL] The script should be in PHP, database is MySQL. The inputs to the script are .CSV; .HTML Tables or .XLS Excel files. The script should be written in such a way that it can be translated easily to other languages. I require all the features [login to view URL] but less expensive. Priority will be given to service providers having a demo for both the web and the admin site. Thank you,
