so from what I've seen the US offers quite low incorporation cost (it appears that you can form an LLC just by a few hundred dollars)
my question is, is there any other country that satisfy these features:
You can do this in Australia.
In addition, Australia has an established legal system and a tax arrangement with the US so you don't get taxed twice on your earnings.
In the UK incorporation of a Ltd company (Limited by shares, not publically tradable) costs a few hundred pounds and corporation tax rates are 21% for profits up to and including £1.5m and 25% above that.
