I'm not sure if you know, but we do not have any direct taxes here in the Cayman's. Perhaps you should check it out, it may work for you, most of the low tax jurisdictions are getting pretty picky whos'e money they will take, however if you can show the source and it is clean, I believe you would find what you are looking for here. I would however advise to deal with worldclass banks only!
Happy shopping!
