I'm going to use free online resources or PokerStars School before spending my money of a "professional"
Well said Albie. Until you have tried all the free learning tools that you can find all over the place, especially here on CC, an idea of a professional coach is a bit unnecessary.
I have advice from one of our Poker Guru's here on CC, and he has been a very good coach, and showing me where I do/ do not play situations correctly. Until you have been playing a while, and struggled with certain situations, you will not know what you need help with.
Go to this area of CC, ------>
Learning Poker where you will find loads of help with your game, once you have searched, read, commented on various things, you will understand a bit more about your game, and then, and only then, should you seek a "poker coach". I do not believe you could contact anyone, with the question "How do I play poker?" that is too broad a subject.
Good luck.
