Hangzhou to Taizhou to Zhoushan

I arrive in Hangzhou by air late afternoon on 7 July (3 or 5 pm) and want to get to Taizhou. What is the best way? I can stay overnight in Hangzhou and go there the next day. Then I need to return to Zhoushan - via Ningbo or Hangzhou?? I'm thinking Ningbo for convenience but is this the quickest and cheapest way? Thanks for any help or suggestions.
