You can use any cheap graphics program - or even free ones like LibreOffice to size and print advertising stickers on a page with a color inkjet. I just do a Google image search for logos/signs I like, save the image file and re-size as needed in a horizontal format that will fit on the barriers.
In my previous track, I had used 1/4" bendable craft foam for barriers in many areas; I just printed the signs onto a full-page peel-n-stick label stock and cut to fit and apply the signage to the barriers. One important note: If you are applying signage to curved barriers, it's probably best to wait until the barriers are in place. When I applied them to a flat surface and then bent the barrier to apply around the curve, the signs inevitably wrinkled over time
