Looking for personal coach

Hi my name is Justin, i'm 14 years old and started playing league about 7 months ago. I have learned very fast from my silver friends teaching me. I'm currently am in bronze 5 from my placements and i am stuck. I want to find someone who is willing to teach me and that is chill and can have a couple of laughs. I am not a stereotypical bronze 5 player. I try to get better from every game and I play to improve not win. I am looking for anyone who knows the game well and is trying to improve as well. I would prefer Gold and up for a coach but i'm just trying to get better. I am open to learning new things and I'm not a very cocky player unless i'm just joking about. My IGN is Itzjustiinn
