Since you are a professional in the business of doing these things, I would imagine that professional equipment is not out of range.

This one can do formlab's recommended 405 nm UV and has a volume that should accommodate anything your printer can produce. This is just an example, there are many on the market that will suit your needs. I suggest looking around a bit after reading the formlabs page I linked above.
I would also add that you should look for units which also have temperature controls, since you are looking for faster cure times. According to formlabs warmer temperatures result in stronger parts with shorter cure time. Perhaps you could contact one of the many companies that manufacture these and see about integrating temperature controls and rotating platform.
