I vote for moving. We moved daughter to club at 8, and while we were playing for a "Flight 1/Gold" team the quality of the coaching staff turned out to be "Flight 3/Bronze" at best. Similar story to yours in terms of losing interest and not having as much fun. We tried doing privates after we realized that damage was being done, but I still feel like she lost a year of development.
Moved the next year and combined a few months of privates with a "Flight 1" level coach and she's back to having fun, learning, and it shows on the field.
Edit: I also have to add that driving your kid to practices/games for an entire season while you see them not improving will take a toll on you as well. It was by far the worst experience I've had as a sports parent. I dreaded the weekends. You might find yourself asking questions like, "How the hell did I not get out while I still could? Have I caused permanent damage? How could I have been so stupid?"
