Get your medical first.
Cant properly remember PPL, but you can get flying done at weekends in the UK (weather permitting) while you finish PPL groundschool probably over 6 months if you REALLY go for it and weather is good. Budget GBP6000. Or can do flying in US over 3 weeks, saving GBP2000.
ATPL groundschool full time was 6-7 months. With job has to be at least 12. Budget GBP2500 and go with Bristol GS
CPL takes 2 weeks full time. Budget GBP4500 in UK, GBP3500 in US.
IR takes 6 weeks full time. Budget GBP11000.
MCC takes one week. Budget GBP2000 (?)
Hope that helps.
