I have a customer who I do a lot of interior signs for but they are now looking for an outdoor interchangeable directory type of sign (something where they can change hours if need be). I'm trying to figure out if I should take on the job or turn it away as this isn't something I normally do and may be too challenging. I have a sign company that I do some work for so I was thinking of recommending them instead. The customer wants me to come by so they can show me where it would be going. I've been to the place of business before so I'm guessing it's either going to be attached to the brick building or possibly glass. They had thought of some plexiglass to go over the signage so it won't be tampered with since it is in a city setting. I was thinking of JRS's Flex Frames or Euro Frames but they are meant for interior. They only have one product for exterior and it doesn't look very easy to switch out signage. Does anyone know of any other product that might work or have any other ideas?
