ISO: Giant 5′-6′ Martini Glass

Looking for a giant 5'-6' Martini Glass. Preferably on the West Coast, but if need be we will ship it. Needs to eventually end up in San Fransisco. Ideal would be to buy something pre-fab, but if you know a fabricator who deals heavily in plastics who could knock this out for us within the next month, we are open to it. Also open to renting long-term (~a month) from a prop house instead of purchasing if you know one that has it. No pre-fab leads. We have searched the depths of the internet only to find 3' and 4' glasses. Anything larger is an hourly rental and comes with a burlesque/aerial dancer inside it. Current fabrication leads are: Pimenta Productions in LIC, NY Plastic Man inc in Vegas Thanks in advance!
