Looking for Coaching tips.

I want to try and get better out of the game so I can carry myself out of silver and try to get into a better elo for season 8. I main jungle and support and my most played champions are. Thresh, Sona, Kindred, Diana. I'm open to learning new junglers and supports. Please get back to me or send me you IGN so I can add you and we can discuss this. I'm a low ELO player I'm not looking to pay for coaching.
