Ultimately, I'd have to agree with Thornir. "I want to do something like Nobleknight.com" may not be a great business strategy; why would someone pick your store over Noble Knight? You need a meaningful point of difference versus your competition.
Now, "like Noble Knight, but cheaper", or "like Noble Knight, but better selection", or "like Noble Knight, but faster shipping", might all be solid strategies (I say "may"; I don't know if those are meaningful issues for NK customers, or if they're something you could deliver on).
