Have you tried Atlantic Flight Training in Coventry?
They run a fully sponsored scheme where you work doing all kinds of odd jobs in return for all the training. I think they bond you for five years after that. Good airline and excellent training. Loads of aircraft too. DC-3. DC-6, ATR42, Metro, electra and others. Well worth taking a look at but dont leave it too long. I think their cut off age is a lot lower than most sponsorships.
Other than that, good luck. Keep trying. If you really want it, you will get there one day.
