First of all thank you very much for your werthful advice and I will stick on to it.
I'm a Sri Lankan living in canton Schwyz. I have an idea of starting a shop with lots of asian products, you might have seen such shops in Zurich. My idea is to make it in the swiss style. Not like the usual Sri lankan shops you see. Main customers I'm looking for are Swiss as I dont have much native people in my region.
