My family and I(five adults) will be going to Nanning from 20-23 April 2013

We have confirmed our flight and accomodation. What I need is a car which can accomodate 5 people, a driver and a tour guide to take us to see the Grand De Tian Waterfall, Mt. Qinxiu and Mt. Daming and also Yangmei Ancient town. Will 2 days be sufficient for this tour? Please let me know how much is the total cost.
Thank you for your help and assistance.
