Working towards opening a FB page as a Travel cons (Geneva)

Hi,

I am aiming to publish a Facebook page as a travel consultant and planner. This is basically to help people arrange all their touring spots and i will also help them with a fully hand crafted itinerary.

But, i have a doubt before i publish this FB page. Do i need to take any government letter/permission before starting up something online in Geneva, swiss?

Please help if this is required and if anyone knows the process for the same.

Thank,
Shraddha
