You should find a friend's garage, shop or hackerspace with a brake, and metal cutting tools.
I have a similar monitor for equipment metrics, and the cardboard design is similar to the stand I made out of metal. I powder coated the metal light beige and it looks professional.
That sounds like a great-looking stand. Maybe you could send me a picture by email, you can find my address on my website. I’d love some inspiration. I also thought about 3D-printing a stand; I just need someone with experience in 3D design to create (or help me create) one, and someone who can print it.
