Most of the flying you want to volunteer for will want a considerable amount of experience if not actually still wanting a CPL or better, the most likely to accept without a CPL is Gliding or Parachute flying but they then want you to have a few hours under your belt, plus a fair amount of Gliding or parachute experience. One way is to get a part share in a PFA aircraft, yes you need a bit of cash to start, but this can be quite a small amount - a two seater can be bought for £15,000 or less and with a 20 person group (the maximum allowed) this works out at £750 each, monthly costs would probably run at £50/month or less and you would then be flying at about £25/hr on top of this. If you do this I would recommend a smaller group if possible for best availability but even with 20 in I do not think you will find this too much of a problem.
