Your total cost will include the follwing (1)+(2)+(3).

(1) Service charge: depends on the rate of your chosen private guide, amount of travelers and days of service.

• Rates are different among private guides - you will enjoy very flexible rate from RMB 300/day to RMB 3,000/day or higher.
• Two clients may share one private tour guide without extra charge. For the 3rd client, extra 50% will be charged. For the 4th client, 75%.
• For half day (4 hours) of service, a 70% of daily rate will be applied.
  
  For example, if you have 3 travelers to share a private guide, and you'd choose a guide with the rate of RMB 800/day to serve 6.5 days, the service charge is:
  The 1st & 2nd traveler: A = RMB 800/day x (6+70%)
  The 3rd traveler: B = A x 50%
  Service charge: A+B = RMB 8,040

The guide will show you valid one-way taxi invoice upon your meeting, and you pay him/her double amount on a daily basis.

(3) Travel expenditure: All cost for transportation, food, ticket, etc during the service, will be travelers' responsibility. Generally, it'd be RMB 100-300 per day per person.
