Private car to pick up at Jiuzhaigou to vist Huanglong then go to airport for 4PM flight

We are a group of 4 friends. I would like to know if we could arrange a car to pick up us from Angelie hotel early morning to go to Huanglong Scenery Park then wait for us at the park. After we finish visiting the park. The car has to send us to the JZG airport to catch the 16.00 flight to Chengdu.

Please let me know if this is possible and how much is it?
