GM or IM Chess Coach

I used to play chess as a kid, managed 1700+ rating in Fide Online Arena in 3+2 and got AIM title. Chess dot com rating is 1550 average in 10+0. Later I left chess dur to work. Sadly, I suffered from a generic disease and lost most of my eyesight. Had to leave work and retire early. I can see a chess board on computer. Want to train for IM title within a year and GM within three years. I get bored because I am confined to a room and don't have much to do so let's start this new journey.
