Correct Print Artwork

We have created a series of scrapbook border designs that were originally done in Photoshop and then saved in Adobe Illustrator as a single layer . Our commercial printer cannot use the files as they require the designs to be done originally in Adobe Illustrator in multilayer so the commercial printer can modify the design to meet size and dimension requirements. The designs repeat every 4 inches, 6 inches or 12 inches depending on the design. An example of this style would be wall paper border material. Attached is a jpeg sample of the first artwork done that needs to be recreated. The original Photoshop files will be provided.
