Looking for climbing partner Wednesday (6th August)

I am in Zurich this week for work and looking for a belay partner to try out Gaswerk. I climb 6a/6a+.
I wasn't planning to bring a rope as I am flying [but can if needed]
Let me know if anyone is interested
P.S. I am South African so don't speak any German/Swiss-German - hopefully not an issue
