Transportation from jiangsu / yuyuan road to pvg

Hello,
Our flight is at 7am and we'll leave from jiangsu yuyuan road.
We are two people + 3 suitcases 20"
The available options I found so far:
- sleep at the airport (try to avoid this as much as possible as I'll be on +21h journey)
- or take a taxi (most expensive)
- or book a car from fliggy program through Alipay,
- or book something similar on taobao (price is strangely cheap so I doubt that)
What could you recommend? Thanks!
