To play CS:GO competitively online

Hello, my name is Choon Hau Chew a 15 y/o from New Zealand. I speak English. I have been the AWPer and main play maker for 2 teams so far. I've had 500+ hours of experience in CS:S and over 600+ hours in CS:GO. I am currently DMG and constantly topfrag/carry in competitive matchmaking games. I have a microphone and Skype. Willing to hear your answer, thanks
