> I would like to take a course that will teach me just like teachers teach in music schools
I hate to be the nay-sayer but you simply will not find this. A video lecture series is absolutely no substitute for a teacher. As a beginner you don't fully understand just how much is involved in learning the piano.
For example, beginners tend to vastly underestimate how difficult it is and how much things like technique matter in piano playing. A teacher will be able to understand where you're strong and where you're weak and what you can do that will give you the most bang for your buck. They will also be able to assess your progress regularly and guide you in the right direction. Once I finally got a teacher 5 years ago, my only regret was not getting one earlier.
I'm sorry to say but learning from solely online resources will be a very slow, inefficient process and you almost definitely will develop bad habits without even knowing it.
Of course, you can still learn from online resources... there are many good YouTube series out there, and Coursera has some courses. Try these:
