URGENT - reliable taxi/minivan service/driver needed for trip from Zurich to Valens

Hello friends,


I hope everyone is doing well. I have an urgent request.


My relatives are travelling from Zurich Marriott Hotel (Flughafen) to Kliniken Valens (7317 Valens) on Tuesday June 03. They will stop in the city center


There are a total of 3 passengers and one is handicapped. They have some luggage and a collapsible wheelchair to carry.


Can you recommend a very safe, reliable taxi service/driver that can provide this service?


Thanks!
