I would play cheap tournaments in your place, and when I see that I am always in ITM around 15% 25%, I would pay a good coach to improve my game so this would increase the buy-in level, the cash game is a lot particularly because many do not like to be stuck, committed to spending hours there playing a tournament, the cash game gives you the freedom, plus the style of play is very different, if you play flop, then believe that start already in your game cash game game needs to be very good so you do not start with much damage! why do not you hire a poker coach to help you plan this? I would do it for sure!
