I lived in South Korea for the past 2 years. I am American. I have been pro in several games, most notably SC2 and CoD.
I have coached several teams into Diamond in both NA and KR.
I do individual coaching and group coaching.
I do a few sessions for free and then after that the pricing can be negotiated but it is very simple and I do bundles.
For example: $-- for 5 lessons of any length etc.
