What part of this fixture makes it for you? Wagon wheel inspired fixtures are sold liberally at all outlets. The shades are unusual--look like upside down plastic cups to me. You could do better.

You could try a Google image search, and you'll find options that are close.. but none are inexpensive. Here are my results.

Probably better just to look at the large fixture websites (like 1800lighting/Capitol LIghting) and see what is available.
