There are other forums that already answer your question.
But I will answer some information for you.
1 good way to transfer gold from YOU > Your Company is Guild Bank, deposit & withdraw.
You can also create a new toon on a vanilla account, once you transfer the gold deposit it to your guild bank then delete the character on the vanilla account. <--This is how I do it.
Of course other people may reply to your response with different suggestions, and opinions. I had person experience with how I did it above and my main account or vanilla account has never been banned and last time I transferred gold was maybe a month ago.
But best of luck to you mate.
