I am challenger booster myself with a lot of success in league.
I can boost anywhere from bronze 5 to master tier, and no task is too big for me.
I currently make a living off of the internet which means I am almost always online, and ready to complete work for you.
Prices and such will be added as soon as I am done doing vouch games for people.
So if you want me to win a promo for you, or just give you a few wins, let me know. ( skype : howtocorki)
