Social Bookmarking Desktop Software - Long Term - Full Time

Please see [login to view URL] for an example of what I need but note that our software needs to be more simplified. There will be almost 3k SB sites (social bookmarking) that we can post to. About 100 will be on unique CMS but the rest will be on the popular CMS such as Scuttle, Pligg and PHPdug. Account creation module, proxy, and posting. Accounts manager so that users can switch between accounts, etc. Details will be discussed later. Thanks for your time.
