Group booking and commission rate:

I have a group of 12 tourists that will travel by trains from Beijing to Qingdao and then from Qingdao to Taishan and from Taishah to Shanghai next Ocotber, 2014. We would like to know if you can book up our train tickets and what is the extra rates you charge on top of regular prices. We would also like travel by train to Chengdu from Shanghai and come back to Shanghai. This is a lot of bookigs. We would like to pick up tickets at Beijing railrood station. Can you arrange this and help us fid the speed train numbers if we provide you with dates and times of the days?
