I don't think i'd pay for coaching, as I feel you can teach yourself very easily. Download top replays, observe first player perspective, take notes of their hotkeys and the way they use them (for instance every zerg user has their own style of using hotkeys to inject hatch).

I personally just study 1 build order, then go and practice for 10~20 games, then i study a new build order and repeat.
