Design and engineer a light weight wood look structure

Looking for someone that can design me a wood look open structure like the attached. That can be joined together in a modular formation, and also secure drapes. Needs to be a lightweight material so the product is light enough to be easily transported to different locations. Also needs to be sturdy enough not to blow over or fall down. Will need the product designed with appropriate engineering. Light weight material recommendations and potentially where to source them from. If you know someone who could manufacture this for me or supply a similar product as well that would be a bonus.
