Journey to becoming stronger. Looking for a Mentor.

As the title says I am looking for a Mentor, a coach who can teach me the ways of League, I am desperately trying to improve and it seems the best option is to have someone who has the time to coach me in this game, I hope to become a professional player and I can't do it by watching random Youtube videos anymore(or streams) I don't have money, as I spent it on upgrading my equipment to get the best possible League experience. So I can't pay anyone... If anyone out there can coach I will list some things:

-Preferably A Mid lane main. -Diamond+

I truly thank anyone who has read this. Good day.
