First of all I am not a legal professional specialised on setting up such structures so my insight is definitely limited. As far as I know the set-up cost for a full asset manager license might be around 100k Euros + as far as BaFin, Finma, FCA is concerned. But thats a rough estimate.
It really depends on many things. But it is not only about to get the license but more about the cost to run the structure according to the requirements.
As far as the professional backgorund is concerned, I really do not know. They all have different and sometimes 'strange' requirements. Generally speaking you need a specialized law firm to help you in such a case.
Anyway if you are interested in my opinions or ideas write me a PM. But again I am not offering/selling any services related to this, nor am I giving any recommendations. I am just interested in the process, thats all
