Shared transfer from Innsbruck airport to St. Anton

Hi
I am landing at Innsbruck airport at 10.20 Thurday March 30th with my son and wondered if anyone landing there at a similar time would like to share a taxi/transfer to St. Anton to reduce the cost.

We are only staying until Sunday so private transfer is the quickest way to get to resort and onto the slopes rather than bus/train.

OR if anyone can recommend a reasonably priced taxi service from St. Anton.

Thank you
