Hongqiao Airport to Shanghai Station

Hi,

I land at Hongqiao Airport at 8 p.m. and need to take a train to suzhou the same night. The last train from HQ station is at 9.10 p.m. which I think I would not be able to make it. How far is SH railway station from HQ airport and how far is South Railway station? And what is the best way to travel there? Would a taxi be very expensive?

Kindly advice
