Ok...this is just way too good to pass up....
How about "Sans A$$ Sign Shop"...or SASS, for short.
And for the tagline: "The asses are gone, and now we make signs...no heein' or hawin', you'll love our designs".
Sounds backwoodsy to me...(which, by the way, is not derogatory in the least bit since we're a bit backwoodsy here as well...Hillsdale, MI).
I'd like to see Johnny Best run with this one....eh, Johnny?
