Hire a taxi to visit Hanging Monastery, Mt. Hengshan and Wooden Pagoda in one day.

Hi there,
I am considering of hiring a taxi to visit Hanging Monastery, Mt. Hengshan and Wooden Pagoda in one day as you suggested. However, I am uncertain as to where I can find these taxi's for hire, how they look like etc. Can you please give me some idea how I can go about hiring one. Also, do I need to reserve them in advance or can I just go and find one on the day.
Many thanks!
