Have you considered an Air Cadets VGS that operate the Vigilant (Grob 109B) ?
Pitch up, work hard, be keen and you'll start getting some free flying, stick with it and after a while you'll find yourself able to take cadets on Famil flights and eventually instruct.
You'll also make a lot of new friends and enjoy a great social scene if its still anything like my old VGS.....!
