Hi
I'm going through the same thing here in Langenthal at the moment.
I found it best just to contact Gastro Suisse in Bern, put everything in their hands. Just google Gastro Suisse for your local offices. At the moment i'm in touch with
www.gastroconsult.ch. These guys do budgets for you, set up a company for you (necessary!) etc.,
Good Luck
