Excellent post and from what I've observed, a good way to help promote your new web host is to offer a heavy discount for the first month to motivate users to give your web host a try in case they're skeptical. I've given several hosts a try because of this as I was able to try them out at a very low fee, for free even at times. As for the uniqueness, the web design can play a role in this, try not to use the same template everyone else has.
