I see it as free experience for yourself, when you are learning money shouldn’t really be a aim, your going to make mistakes and the “buyer” wont be impressed. I wouldn’t play for free all year or anything like that, maybe 5 sets? Then i would offer 1 free set at a club to prove i am good enough for a buck, mights also show them you are keen for busniss at there club. I don’t want to earn thousands in my beginning stage i find it fun and good experience for the future.
