Hub motors available commercially?

I'm trying to find a single shaft hub motor in the 20 to 30 kW range. Elaphe doesn't sell retail, neither does Protean, YASA is ridiculously expensive and way too much power. The only other I found was QS motor, but the largest single shaft hub motor they sell is only rated at 12/24KW. That would work ok, but performance would be pretty anemic.

Does anyone know of any other single shaft hub motors that are selling retail?
