My smurf account is unranked, my main account is Diamond. I can duo queue boost Bronze/Silvers/Golds into plat pretty easily with my smurf.
I can also log your account and boost you if you wanted it done faster and easier. (I have never logged anyone elses account as of yet so we wouldn't be flagged for it)
Ideally I'd like to boost someone in exchange for lifetime clraik VIP. Most boosting sites charge an arm and a leg
eg. First site I checked charges 154$ USD to go from Silver V to gold V. Lifetime VIP is half of that.
