As you say you have NO scottish connection. have a look at Isle of Skye.

Beautiful universal tartan (meaning anyone can wear it) with the added bonus of instant membership to the Global IoS owners club (I don't think you get a certificate or a badge though )

There are lots of pictures on here to help you see what it looks like made up (use the search facility in the 'show us your pics' section).

One thing though, beware of cheap (and frankly nasty) imitations.

As you are in North America, speak to, or email Freedom Kilts or USA kilts through the sponsors links on here for the real deal and more info regarding pricing.
