Where are you based?
In the U.S. NYC rules but pretty much everything is expensive.
Good point about Prague.
Where do your friends go besides the States if they want to make good money? London?
Depends... quality or quality for your buck like so many on who want to pay the lowest possible price for a full service.
NYC and SF have everything.
Cheaper prices in Rio de Janeiro, Prague, etc.
