Car Rental in Zhuhai

Hi,

We are planning to be in Zhuhai for two weeks in Feburary and would like to rent a mini van with seat belts. We have two young children so the minivan needs to be with safety standards and therefore seatbelts are critical as we will have child car seats - do you know any car agencies who rent cars for visitors in Zhuhai? We are U.S. citizens but one of our relatives who has valid driver license in Zhuhai can drive us around. We do not need drivers to accompany us, but just want to rent a decent car. How much would something like this cost for two weeks?
