At the end of June I resigned from my country club after being an active member for more than eight years. While I was a member I volunteered my IT services on numerous occasions, and I became the "go-to" guy for our club manager, a very decent guy who is working on a very tight budget. Lots of us volunteer our various services that way for the club and I wasn't all that special, I just had a special skills set they needed that few could provide.
Fast forward two months, the club needs some IT work done and their very tight budget hasn't changed. Rather than pay some company $100 an hour the club manager contacts me. Of course I am no longer volunteering at this point, I have no skin in the game (for three years or so anyway, I would like to rejoin after achieving FI). I recently did five hours of work for them at a rate of one hour for one greens fee.
So at the end of the day I get to keep golfing through the fall, and the club hasn't gone out of pocket for services rendered. Total win-win for both parties!
