Great job!
It's very timely for Matt Cutt's recent blog post -

Which mentions this site
http://www.stclaire.com/go/industrial_signage/sb2/html , in which you can create your own sign.
Too bad he didn't find your site first. I'd suggest posting on all the social bookmarking and forum sites you can find. Those are the people that would be eager for your site.
Certainly, your's has a happier feel. The domain name is very easy to remember, the site design is easy to follow, and coloration blends well. You have created some awesome linkbait.
Incidentally, I added it to StumbleUpon as the first reviewer.
