I may not have a website (yet) or a cool name, but I work with bands very closely to make sure that the songs that I chart are not only fun for the players, but that the bands involved feel the chart adds to their music instead of distracting the players' attention away from it.
I have a preview available here: http://www.youtube.com/watch?v=GNFQHhdd1Z8 and will hopefully have a better preview soon.
I also have very flexible fees, whether you'd like to pay upfront and keep all the sales revenue, or split the revenues. I operate under the idea that the band has done all the hard work in this process, and that a 50-50 revenue split is insulting to the band.
If you're interested, drop me a line at firstname.lastname@example.org with "Rock Band Network" in the subject line.
