Looking to Learn

So ive been into league for a while now, but i havent ever really ventured outside of Co-OP vs AI games. I like to think i have the basics pretty well down i just need some help when it comes to character building and playing on a team. Would really like to make it to ranked this year, willing to learn and play often if someones willing to teach, or even join a team (role is flexible). IGN is same as listed anyone willing to help out is much appreciated! EDIT: Summoner lvl 23 and i can try to learn to play as anyone, have about 20 characters unlocked.
