cant really offer much advice about civvy flying but there is a wealth of information on this site alone if you do a search.
But the basics are get sponsorship/part sponsorship with an airline which is very rare and very competitive. Alternatively you can get your PPL hours build/instruct to pay the bills build the hours, then pay to do all your CPL exams, intrsument rating and type conversion and then get a frozen ATPL, send out loads of cv's and try to get a job!
Or join the RAF as the Queen has more aeroplanes than everyone else and she will teach you for free!
