I think you can just go to any big sports shop. I went to Athleticum in Meyrin, its costed me around 30-40 CHF

There is a great surf shop in GD Saconnex - Techno Surf.

Everybody says the service is really good

I always felt that in Switzerland they charge too much for something as simple as service. I go to Lanches Sport in Annemasse (nearby France). A normal service costs 13 euros and it includes treatment with hot wax which repairs most of the shallow scratches, and sharpening the edges. I was always very happy with their work. A full service costs 30 euros and then they do EVERYTHING. Oh and I asked them nicely and it was ready the same day.
