Just a suggestion....
How about getting yourself an A/G licence and doing the radio at your (or a) local airfield? It won't cost you much, you'll be in the environment and earning a few quid to boot. Be sociable and keen, and you might just make a useful contact here and there. At that level, no airfield operator is going to mind if your ambition ultimatley is to fly. You're a useful stop-gap.
Ten years ago, I worked at an airfield doing just that (my own story is an aside, I'm an ATCO now), and I met I lovely young chap of 16 who washed aircraft to pay for his lessons. He now flies B757s.
One thing I have learnt about getting on in this industry - much of it is about being personable and taking opportunities where/when they occur. The rest of it is down to you and your ability and determination to succeed.
Good luck
