Develop Amazon Cloundfront Script/App

Hi, 1st thing is i have no idea what this should/will cost so at the minute i'm looking for prices and will possibly go ahead I run a web hosting company and have recently found amazon Cloudfront which i think is amazing i would like someone to create me a script/modify something that already exists to do the following: Allow me to create/manage users (possibly automated through WHMCS) Allow users to create/manage Amazon Distributions have a script that monitors the users current cost/bandwidth(i would set the limit/no limit) (cron jobs would be used i think for this) usage so they can be disabled and not go over their allowance/agreed spend limit. i'm actually quite surprised that someone's not done this before but on looking i couldn't find anything but could be wrong. joe
