Where to get coaching these days?

I'm 700 mmr and think I'm at least 4k casually and 5k if trying. Like really good game sense really good micro and really good hero knowledge and decision making of all sorts. I've mained oracle arc tinker voker and play timber and puck for fun. I even made a video of me playing like 10 years ago when I was comparitively bad. Link:

My problem is consistency over time like I just play ranked drunk or just intentionally going to farm 3 moon shards for the lols. I got a real problem with consistency both in game tomfoolery and irl (drinking etc).

Is there a coach that can help me?

I think I have a mic but would buy a modern one from Amazon. I wouldn't mind being on stream. And I don't mind what hero I play, marci, mid, support, anything.

BUT I live in Japan so time problem is real. USE or sea or JP server ok.

I do have PayPal but I think I can't use it because Japan but I can use international credit card.

Anyone help me
