Hi, Mr Ting. Sorry to tell that there is no direct bullet train from the airport to Pudong.
You can get to to Hangzhou Railway Station first and then change to bullet trains to Shanghai. Hangzhou Huanglong Sports center has direct bus to Pudong Airport. The journey may cost three hours by bus. Bullet trains: half a hour or so and you still need to take another bus to Pudong.
If by taxi, you may pay more than 800yuan. It is too expensive.
