Isn't wise better for receiving? I can't work out how one sends from here to a foreign account using them.
Otherwise I've used Shyft, they are great in most cases. Better rates than the banks and EasyEquities.
OPs request is a bit vague. There are many ways to get money offshore (most if not all local banks can so it, EE can do it, Shyft can do it, other methods I'm not aware of probably exist too) and they are all legal.
