a few guys I know got themselves into pilot jobs through internal recruitment. One via cabin crew and used the money to get their cpl via modular route and the other as a dispatcher. Both roles put them in front of flight crew and gave them inside info on recruitment. As they were respected by the flight crews for what they were doing and how they were doing it the senior pilots put in some good words and levered the door open which gave them a chance to prove they were ready. I would say this works in either a smaller airline or a medium sized one at a smaller base as you get to know people. I can't see it working in big airlines that run very set recruitment policies.
I would explore the RAF, Navy and possibly the army (careful with that last one as you are a soldier first then a pilot)
Any parachuting near you? Maybe you can volunteer there. This may enable you to again work towards your CPL/PPL and get into the aircraft as a drop master or just to assist the pilot. Its all a start
good luck
