Does the hardware with the dimensions I need actually exist?

I have been searching Amazon, Lowe’s, Home Depot, and several custom cabinets sites and am starting to wonder if this hardware actually exists.

I’m looking for a D-side Lazy Susan, 20-21 inch diameter that will fit in a 33 inch tall cabinet, with three tiers. If this cabinet was taller, it would have been trivial, but 33 inches seems to stump the onlines.

At this point, I’m not even where else to search it how to alert my query. Do I need to contact one of these companies and just ask? If anyone knows where I might look, please share.
