my6812 motor/drive

I'm trying to purchase the motor that comes with the my6812gz - 150 watt golf cart motor. It is made by Zhejiang unite motor co. Ltd, China. I can get to there internet sight but they only sell in quantities of 1000 or more and I only need a couple of them. Does any one out there have any Ideas as how one could find a distriutor here in the US that stocks these motor drives>
