Do your training around your current job, and keep earning the whole time. Integrated schemes are both expensive and slow. Going modular you will not take 18 months, and crucially you'll have money coming in the whole time. Start studying the theory today. Get your PPL exams done, then take 3/4 weeks off and do your PPL at an intensive school. Keep working and studying for the ATPL theory(which, by the way, is NOT that hard-a lot of info but nothing difficult). If it's possible to build hours while you work and study for the theory then so much the better. That way once you've done those exams it's just another 4-6 week course for CPL and ME-IR. Back to work for a while and then 10-14 days for MCC-JOC. Remember, if you're dedicated and prepare a lot at home then the actual flying courses do not take long at all and don't have to cost crazy money. You could do it for 40k or so if you're savvy. Almost a fact of life that you'll need 20-30k for a type rating afterwards though. Good luck in any case.
