"astronomical fees"? Do you want to set up a trust on the moon?

I often read that on this forum and I am a bit surprised... you are the client, so if you instruct clearly what you want and define a budget, no reason for paying "astronomical" fees... If you go to an advisor and ask him: "tell me what I can do with that", he will probably spend hours and hours on it as there are hundreds of possibilities to structure a business. But in your case, it seems that you know pretty much what you want, therefore your questions are very clear and on specific details you want to know. Therefore how could fees be "astronomical"? Except if you go to a Big 4 office or to a "flashy star tax attorney" (as there are some in CH, not at all at the level they pretend to be...), I don't see how you could end up with significant fees.

You know better than any one else how you want to run your business and how you want to manage your risks, but if I had a Russian client basically lending me CHF 1 Mio, I would prefer covering my a** with a written external advice and put this forward to my client rather than telling him "Trust me it works" and have him knocking at my door with 5 friends late at night once everything went wrong Dont' take me wrong, I'm joking, but sometime it's better to spend some CHF in external advice, nobody can sort out everything by himself, especially over the internet.
