I have been a casual player intermittently for a good few years, more recently I have been playing a little more seriously, 2x 2hour sessions per week. Elements of my game have inproved a lot, the purchase of a new racket has transformed my short game, my serves are getting to the point where I can put the shuttle within reason where I want with some regularity.. However there are other aspects that need work, back hand and especially high backhand clears are real nemesis shots ... We have been asked to join a doubles league, I am keen to do so but would like to get some coaching or help with my mediocre playing .

I live in Portsmouth uk, I have done some internet searches, whilst it seems there is a good badminton scene I cannot find any coaching... Finances are tight .. Any suggestions ?
