In my experience, not many people will give up their own time to coach someone for free.
I recommend you use your time to use the free chess puzzle trainers on the internet to get better.
Looking for coach
This guy offers his first lesson for free: https://www.chess.com/member/santiagomagno15
If you want more lessons after the first one you have to pay.
This guy was offering free lessons but I do not know whether or not the offer still stands (it is possible that he has started charging now): https://www.chess.com/forum/view/chess-lessons/free-lessons-6

Some clubs have mentorship programmes where you are paired with someone more experienced who will play casual games with you and offer you advice.
If it helps we can play an unrated daily game together and do an analysis afterwards. I don't offer a real coaching service but am happy to give out a few tips for folks who are getting started.
There are also a lot of ways that you can improve without a coach. A lot of people write blogs and other articles for free. There are too many to mention.
There is the mobile app Learn Chess with Dr Wolf which has an AI coach. It is not as good as a human coach but is still quite good. The app has the first few coaching sessions for free and then you have to pay if you want more.
I’m a beginner at chess and i’m wondering if there’s anyone who could coach me for free! I’m quite young and still in school so I won’t be able to play everyday but I will be trying my best!
