Good to see you taking on the great advice on offer here. It's kind of been conveyed in the posts above, but given your last post, I just want to say it explicitly:
If you initially just want to have a couple of flights in a small aircraft to see what it's like, wander down to a flying club of your choice, say you are interested, and ask if anyone is prepared to have you on board as a passenger next time they go up. Just because "Joe Public" expects to pay £150+ for a short trip doesn't mean you have to, it's just they don't realise that many many private pilots banging in the hours would be more than happy to have some company and get bunged a few quid for share of the fuel (agree the contribution before you go up). Despite some posters on here (who may or may not actually be pilots), the private flying community as far as I've seen it is very friendly, and very keen to share knowledge and experience with anyone who is interested. (Oh, BTW, nothing against the non-private flying community, just don't have first-hand experience of them. Phew
)
Lastly, just to point out as well that the reason you can't pay more than your share of the fuel bill is that they'd be deemed to be earning money from it, which is strictly prohibited for a private (non-commercial) licence. Having paid anything up to your share of the fuel bill however, there's nothing to stop you buying the friendly pilot some beers in the clubhouse eh FleetFlyer?
