I am not either of the two 2.3k players doing the elo boosting service I just get a small cut of the money if you say I referred you to them (so please tell them).
Two 2.3k+ players have been doing elo boosting services for about 1-2 months and have completed about 30 jobs since then (they can provide screenshots of graphs from lolking from when they started and finished).
This link will provide you the basic info and how to contact these two players and they are usually on from 12pm pst to 3am pst on weekdays and all the time on weekends:
If you have any questions I would suggest asking them two because I won't be too active on this thread.
Remember to tell them fatpancake sent you
