Thank you miniMia,

That is very useful info.
I am still reading Help for Businesses/Freelancers in CH
but got confused with the different types of companies that are being dealt with in that thread, i do know Richard has a wealth of knowledge on all subjects it seems, he is like the walking business Bible.
the response i gave in my post is because these are the things i am still reading about and am trying to figure out. not if there is a market for my products etc, i will go back to reading more about it.
and it is no problem that you mentioned that there are plenty of links that tell all this. i am sure i will come across them or have already i first want to finish reading a few threads. before i start reading all the links i gathered.(English - German ones)
Thanks again

Cheers,
Jaak
