Shared Files Search Script - Search Engine for Shared Files

Hello all , I am looking for a shared files search engine script. Examples of websites using similar script : [login to view URL] [login to view URL] [login to view URL] [login to view URL] What this script basically does is it crawls websites for rapidshare , megaupload , filestube and other file sharing links. If you use any of the above websites you will understand the whole concept. I also want a wide range of features on this script. I don't want an exact clone but anyone who can do this job, please contact. I also want you to show me some previous work of yours. I am not looking for freshers, looking for an experienced programmer.
