Transport for 8 persons from Jiuhuang Airport to Jiuzhaigou

Hi
I would like to know what is the best option of transport for 8 persons (with luggages) at Jiuhuang Airport to Huang Loong Park and JZG? Can one minibus cater for our group? How much does it cost for this route in the peak season (Oct)? Can we also book the same minibus for our return (from JZG to the Airport)? Thanks in advance.
