I would continue to study. Get a solid foundation and find a chess coach later. This way when you begin, you coach should be able to build on that foundation more easily. I think you would be surprised at how much accumulated knowledge you already have but just don't know how to use. If you keep building on that (think of a sponge) then you should get more out of a coach.
Much of the above is just a theory I have recently been mulling over...but I believe it may be close to the truth.
Alternatively go ahead and get a coach. My theory may well be incorrect and if you are willing to put in the work and be under someone then you could potentially get a lot out of it.
I was considering getting a chess coach since i feel like i have reached the highest i can get playing and studying on my own. I wanted to know if having some lessons make a big difference, or if i just need to put in more work with the books and game analysis.
