Is there anybody who knows about how to run a conference in Switzerland?
I am a master student and I have to write a business plan for conference.
I was wondering if anyone could help or gave a source for following topics:
Regulation
tax
venue
Sponsorship
advertisement
Set up cost
or have an experience about running a conference.

Er.... ask your thesis advisor?

This isn't something a master's student should be left to do singlehandedly.

Unless of course it's not an actual conference, just a planning exercise - maybe you are getting a master's in conference planning or some such?

well,it is not a thesis.it is for a course of business plan.What I am looking for is more about regulation and start up cost and those stuff.
because I am foreigner, I am a bit confuse about different rules which each canton has and unfortunately most of the information is in German or the language other than English.

With so many questions, it sounds like you are really out of your depth. I would suggest you ask the person who asked you to perform this task to give you guidance or ask who did it the last time.

Thx for suggestion.it is not like I do not know about how to run conference but I am wondering if there is any regulation or legal issue in Switzerland.
I wrote the rest if you have any idea, I strongly believe that we different people could have unique idea since they take look from their own point of view.
The business plan is not about the real one and therefore I there is no previuse experience.
In other course which we had (entrepreneurship) I gave an idea of running kind of conference and professor as was the same and knows about my idea sk me to write a business plan for it as well.
Basically I need to write a business plan for a typical conference,therefore as an initial point I have to know about the regulation for start-up company and running a conference.
If you know any website which is written about this kind of regulation it could help a lot.
