1000 is quite reachable without any coaching or even help from a decent player.
I glanced through your last 5 games. I instantly could spot that you aren't always following basic opening principles, blundering and missing tactics, too many pawn moves, making unfavorable trades, and extremely passive play.
My recommendation would be to play principled in the opening, work on tactics and not hanging pieces, and getting your pieces to be more active.
From my own analysis I would say my biggest areas I struggle are simple blunders from rushing moves, inconsistent openings, and not properly blunder checking. I also find myself executing without a plan and realigning heavily on intuition in unfamiliar positions which doesn't always pay off.
