electric golf cart

I want to buy for distribution in NZ as sole agent: A ride-on scooter or trolley or cart suitable for one person. It must be foldable or otherwise able to transported in a car trunk. It must also be capable of climbing 15 degree slope. I can sell approximately 50 of these each year. Would need to import one sample only for evaluation before purchasing in quantity. Please only contact me if you are the product manufacturer. If made in China all purchases will be made through my agent in Dongying, Shandong Province.
