Amazon PHP Repricing Script

Hi, I'm looking for a typical Amazon Repricing Script, written in PHP and using the Amazon APIs. That means I need a script that checks and updates the pricing information of various articles on Amazon depending on the price development of my competitors. The script must be executable via cron on any root server. Mainly I'm looking for an already developed script that you have in stock and can sell !!! However, if you rather develop from scratch, I need you to offer me a feature list of the script, not the other way round. Thus I want to make sure that you have the understanding of how an Amazon Repricing Script must work. I have no time to write a long list of wished features etc., this is your part, too. So if you bid for developing a new script, you must bid this way: I offer the script and it works _like this_ and I include _these features_. Thank you!
