Doing business here is tough.
If it is a small operation, not really a problem, but when you are a larger business or an incorporated business and on the tax radar and with a dozen plus employees, it takes on a whole new dimension.
It is not to say that it is not rewarding. But as a newcomer without contacts you will find it difficult. I know may successful people her, some who have made millions, but I have seen hundreds come and go blowing everything they had.
I bought into my first business here in 2003, after 7 trips ranging from a week to a month. Things were way simple back then, thing are not simple now.
My advice is start small, do not incorporate and do not invest what you cannot afford to lose.
Why are you so pessimist ?
If you don't pay taxes (and don't speak the language) you will be in trouble. If you do pay taxes (and don't speak the language) you will be in bigger trouble. 1000's of (foreign) small businesses have got by in the past avoiding the tax net, but the tax authorities are bearing down ever tighter these days.
Good luck.
