Hiring a driver for a week in Henan

I travel independently and like to hire a driver for a week to go to Zhengzhou, Dangfeng,Luoyang, Longmen,
Jiaozuo (Climb Yuntai mountain), climb Songshan etc. Who should I contact? I will arrange for all my
accommodations and logistics, as I speak the language, and do not need a tour guide. I have used public
transportation on my previous trips, and now want some luxury and save time.
I also need a driver for the Xian area, and Huangshan/Jiuhua shan area. Thanks, Kris
