Coaching recommendation

Dear chess friends:

I am in the process of selecting a chess coach ; I know there are certain common sense criteria when picking a coach but it is very difficult given so many coaches from all over the world to choose from, unfortunately no public reviews are available at chess.com

Please send me a private message if you know of a coach you worked or are working with and getting positive results that can help me improve on ALL aspects in the game; greatly appreciated if you can give a brief comment also

As a reference I am 1300 USCF 1600s in chess.com. Thank you so much. Wilson

Why do you need a coach?
Buy a book by a top grandmaster: pay $20 for more than 200 h of top notch coaching, or 0.1 $/h
Coaching by a top grandmaster would cost you 200 $/h * 200 h = 40000 $
