Your best bet would be to try to find a place that sells stunt bike parts. Typically that niche market isn't concerned about speed but power to do their tricks...Which is promising for what you need.
It's for an electric motorcycle, so nothing is stock anymore. I found one vendor (actually it's my friend's dad's place) that has sprockets up in the 70 tooth range, but they're asking $125 for the anodized aluminum sprockets.
