I am working with a customer who left a major realty company to start her own. She is looking for prices on .040 24" x 24" double sided aluminum signs, as well as 18" x 24" Arrow shaped 4mm coro signs. The prices she says she used to get are insanely low. I believe it was a discount because of her companies buying power. Never the less figured it could not hurt to see if anyone knows a trade wholesaler for these items that maybe I don't have in ye olde rolodex yet. Any help is greatly appreciated. Thanks!
