Cohesive Internet Structure and Marketing Campaign

I am looking for someone with experience and a proven track record to utilize all social media forums and build a cohesive image for my music artist brand and help me promote it through these forums, as well as other internet forums. Specifically (but not limited to) opening up twitter, facebook, myspace, and all other accounts with one cohesive look, and then market it to get a mass following. We will be promoting music, but even more so, promoting a brand. This will expand to other forms of media outside of the music world, so we must keep that in mind.
