Looking for high elo mentor (Preferably Platinum and above)

Hi everyone my summoner name is Hundley. I've been playing League ever since I learned the Mac Beta had been made available, for me that was May of 2013 so I've been playing for 9 months. I just recently started playing ranked in December after finally deciding that I've been playing with some average Silver IV to Silver II players that are friends of mine. I was placed in Silver IV in the preseason and almost made it to Silver II before the preseason ended. This season I went on a losing streak, some due to myself others due to the lack of teamwork between my fellow teammates and myself in que, and was placed in Bronze III. I'm going to be playing lots of ranked from now on, at least 4-5 games a week of solo que and another 2-3 a week of ranked 5s with friends. I'm looking for someone who knows the game mechanics very well, also preferably knows a lot about laning in general but more so as it pertains to mid and top (being well rounded in every role would be ideal so that I can learn to fill when I don't get my pick). I'm looking for someone who would do this for free, as well as to get some practice for themselves, preferably someone that is in Platinum or above, however Gold will be fine as well, I just want someone that is willing to coach me for free and help me with all aspects of the game.
