Kay,
you know what, I had a friend working at Kinko's and he did several HT signs quite cheap for me (thick vynil printing). My suggestion though: take a print of your idea at your nearest Kinko's and talk directly with the artist and I'm sure you'll get things done for a fair price indeed. You can download all logos easily thru internet, though.
Afterwards, just get some nice'n fancy wood frames and you'll be done
Regards, Chuck
