just to clarify, you are offering, cause you are new to the forum, 2x free "vouche" placement matches.
but you are just telling that you a "good" player will play them for you, the price is kinda low compared to others, its even in $$ not €€, so we can assume you sit in NA?
moreover what about the 10 games, "offering" 9/10 wins (or atleast g5 start (if similiar mmr before)? is it single player placement or would you duo with 2 boosters (to remove risk + ensure wins) or even offering duo (owner + booster) ?
you may should give us some more information (and if the answers are satisfying i would consider taking your offer
if not taken already)
and free push
