I have a customer in need of new signage for his tradeshow booth. He tells me they are somewhat rigid, I am thinking a lexan type of material. I would appreciate some advice on what type of material I could use, is a matte banner totally out of the question? Is that cheezey? I hate to order a $500.00 roll of something I might use only once a year. He also tells me he wants them by next Friday. Any guidance will be appreciated.
