Looking for a REAL coach/mentor

Hello, guys! Hope ya'll having a good day.
Alright so, My name is eddye, i've been playing DotA for about 5 years. I'm former DotA 1 player and just started playing Dota 2. I would rate my in-game skills as mid/adavanced level.
My goal is basically becoming a better player and then joining the competitive scene.
I've already tried out some of those so-called mentors from this thread.
Yesterday I played two games with Sir Azar Claden. First game he played slark and to be honest I didn't see him doing anything decent in that game at all. Anyways, we were to play a second game where he supposedly disconnected, not sure if it was a real disconnect since a couple of minutes later he showed up on steam and he didn't even bother getting back to the game. Anyways, in short, he's just a very low skilled player, not even close to what I expected from a mentor.
Some hours later I played a game with Pu12e. He failed hard at solo'ing mid and also did some clear wrong moves throughtout the game and started talking nonsenses losing it + right after the game was finished,for no apparent reason he kicked me out of his party without giving me any feedback. IMO he's more like a clown.
Well, as you guys can see I really take this game seriously and I really wanna get better at this.
Btw, I'm from Brazil, but i have no problem playing on US/EU bots and even though English isn't my native language, I can understand it pretty well.
Thank you guys for reading my post, if you're interested in being my coach/mentor do please add on steam. My steam account is : GodPlzKillThemAll
not sure if there's someone else with the same account name, anyways my real name is Eddye.
I promise I'll be a very dedicated student.
