proxy hit generator

hi, I need a hit generator that will get ip addresses and hit any site that I assign to it. It just needs to be simple, I will want it to create original hits that will fool topsite scripts especially Aardvark Topsites PHP 5.0.1. It will need to be able to appear to come from search engines or any other site or sites that I would want the hit to originate from, and make random hits per hour and per day. If you already have one built that is great, I will want full rights to the script though and a little customization. Thank you
