I have a clematis that came with bamboo supports to hold it up; 3 kind of teepeeish. I'd just get a tomato wire/cage or something or even an interesting stick/branch with a few "prongs" still left on it and use that.

I had a rose in my old yard that was/is beautiful. You don't have a nursery near you? They could probably order the climbing yellow if they don't have one.
