Not sure what kind of sign your looking for but ive had 3 made from a little shop in gatlingburg 2 small ones for my house and camper and 1 large one for the farm all three were very nice and have lasted 7 years and counting the web site is www.signsofgatlinburg.com
I was interested in the two answers to emoore's question so I tried the websites listed. Unfortunately neither of them worked, so I did some searching and found these listed below. I think they are the ones that deerslayer and mastercraft were referring to. www.woodsignsofgatlinburg.com www.3dwoodcraft.com I am not a good typist so I cut and pasted the addresses. Hopefully they are correct. Also if you "google" or "yahoo" wooden signs you will get a lot more listings, but it is always good to have someone's recommendation.
I know this is an old thread, but i just wanted to add that I make wood signs for campers/houses/etc. www.engravedwoodsigns.com I think they look nice but of course I am biased!
