Hi Arian
I am a British gweipo with RP accent. I have been in Hong Kong for more than 15 years. Previously I was a lawyer and more recently I have been engaged in teaching business professionals (including native and non-native speakers) to improve their English presentation and writing skills.
I can certainly help you with your business English, including colloquialisms, pronunciation and grammar.
You can contact me at

Louise
