Dear Farid Nasser,
Thanks for contacting Top China Travel!
For your first question, there is no bus from Hangzhou airport to Shanghai, if you want to go from Hangzhou airport to Shanghai, you can take taxi but it will cost a lot for maybe 500 Yuan. If you do not want to take taxi, you can go to Hangzhou railway station to take train to Shanghai.
For your second question, we can send you the cost for Zhujiajiao tour from Shanghai of 5 people, later you will get email from Maggie.
Any further request or question, please feel free to contact with us.
