Having trouble finding a vendor for round aluminum sign blanks.
I did a bunch of these a few years ago. Client wanted 24'' x 24'' round real estate signs. I made a circle cutting jig for the band saw, Cut 3mm BeBond and installed a print to each side. I also created the rider signs on the bottom that had a curve in the top. Installed grommets for hanging.
any local sign shop can do that with waterjet or cnc router some may have issues reproducing that logo but you would have to ask
