Need Script/Tool for PR

We need a script or tool that will allow us to check PR of sites massively and not be restricted to a few hundred at a time. We shoudl be able to enter thousands at a go. Tool should have proxies built in , delay of requests, randomize the delay time, remove duplicate urls, and give us report via email and / or csv file. Also should have the ability to load. delete, modify proxies If you have a working demo would be great Thanks
