LF Training

Basically I am sick of soloing. I get matched with people who tend to put me on tilt with their terrible attitudes because they lost. I play much better than my rank and mmr as 9/10 times I am the highest gold in game, cs in game, dmg to champs in game. I basically am looking for people to solo with on a very consistent basis (every day) for at least a couple matches if not more. I want to get better, I don't care if I climb the teir ladder, I just want to get better at the game, and I cannot do that by myself. I am looking for high teir players, Plat+ to help me achive my goal.
