Unfortunately i cant directly state his IGN. But you could easily find him on the ladder by searching it yourself. This is just to protect ourselves so we can deny being boosters at anytime. Our team tag is TLB.
Ill work on getting vids of him,it may take some time as im managing a few other things and players.
Heres our reviews though if you were interested in purchasing a coaching session
