... clear decal film printed in a color printer...

If no other/better solution can be found I will collect all the signs/artwork I would like to have and print them all together on one sheet. I think one page per layout is affordable
But there is another surprise. The companies with the most fancy artwork at the walls have the most boring web pages. Might be you spend the marketing budget either for wall painting or web design but not both.
