Small British Market

Hello Britain lovers and expats, how do you like the idea of organising a small British Market in Switzerland? With producers and sellers of British products, tastings, music, a pop-up tearoom and of course lots of bunting. I think the market could take place anywhere in Switzerland but Zurich might be ideal.
I so love the idea of a British Market, I'm prepared to actually organise it. However, I've never done something like this before and I don't know where to start. Do you have any helpful tips in organising a market or do you even want to join me in organising it? I'm a 30 years old lover of British bliss, living near St.Gallen. Looking forward to hear from you! Alexandra
