You don't have a lot of choices.

You can have your own script made.
You can use scrypted - scrypted.com/scryptedcms.html
You can use xeonlogic - xeonlogic.com/xeonreviews.html
You can use Gossimer Links - gossamer-threads.com/scripts/links-sql/index.htm
You can use something like Joomla and their JoomlaRatings plugin.
