4x10 Acrylic Sheets (Red)

Does anyone know where I can find some? I can get them in 72x120 and 4x6, and 4x8, but I need 4x10's. We have a project we are bidding where the letters are about 50" tall each letter and we need to fit two letters per sheet for faces of channel letters. I'd hate to have to use 1 4x8 for every letter. What a waste.


I have tried Regal Plastics and Laird. Waiting on Allied.
