If you really want to do it, then (assuming you’re in the U.K.) shop around the flying clubs and do a PPL, IMC and night rating for about £12k in an old C150, get a share in something cheap or negotiate a deal for hours building, self study for the CPL exams, and then get an instructors rating. Spread that over two or three years and you can then start getting paid to fly and it will have cost you about £30k if you’re careful. Keep instructing and work at your day job, and then to a CBIR and eventually the CPL and the other stuff part time when the market starts to pick up. Don’t even think about giving up a job /career for a full time integrated course, what ever the big schools might say...
