Working vinyl mini-blinds (Colo Blvd/ Hampden)

Hey Campers! I'm looking for some working mini-blinds. They don't have to be pretty, but they do have to work. I'll be needing to cover a west window this summer, or we'll fry. It's gonna be a hot one! 42" wide x 54" long. Mounting hardware not required - but it would be a bonus. Thanks!!
