Branded Universal Instant Messenger

I need someone who can help me setup a branded universal instant messenger from existing oopen source software. I want to include yahoo, msn, googletalk, skype, aim, and icq, plus any other significant messenger players and put them all into one messenger...including making use of their VOIP capabilities. I need account creation and download of My Universal Instant Messenger (whatever it will be called) to be integrated as part of the signup procedure for other free services I will be offering such as email and webspace (see other projects I have currently running "Automated Sitebuilder..." and "Automated Squirrelmail"
