I have a client that needs 1000 6"x6" lawn posting signs for when they treat lawns for bugs. This is required legally, super basic. We usually build signs and do big vinyl so high volume print jobs are usually subbed out and marked up. The vendors I am seeing out there for this only offer retail(consumer)pricing. If I could do this in house it would be killer. I'm thinking thin printable polystyrene .032? trimming is super easy just score, fold, done. 2 holes for coin stakes or whatever stakes I can get. or some economic weather resistant poly paper, these only need to be out for 48 hours then thrown away. would be 2 colors: yellow BG, and black copy. any insight would be great!
