I'd recommend the metro, I'm not sure on exact price for this (less than 20rmb). This way you're avoiding traffic.

Taxi will take a minimum of 1 hour and a half, double that during heavy traffic. The cost will be 180rmb to 230rmb, or more if stuck in traffic.

There is now a metro straight from HQ to PVG.

Hi, the cost is about 9RMB but you should expect to spend about 2hrs in travel time between them on the metro. Line #2 is very long (I think 33 stations) and very busy. While taxis are more expensive 200RMB, you will get there faster if the traffic is normal.... if its peak hour... well it doesnt really matter which one you use : )
