Silver Support looking for High ELO Mentor

I recently escaped bronze and now want to be a better support and play on ranked 5's teams. When i support in norms ( with a duo) its usually a stomp because i actually know what to do. But when I do ranked 5's i just feel.. powerless. i have a severally less impactive feel and even loss lane sometime and i just don't know why. So Im here looking for a Higher Elo player to pretty much just do norms with me to raise the skill of my enemy and tell me what to do and what not to do and when. I play : Thresh Morgana Nami Nautalius...Learning: Sona Soraka Taric
