Hi, this is actually my first post to, i am based in and just finished my training in the UK so my experience will not cover india but at least then you have one country covered.
I did an integrated training course at Oxford avaition academy giving me a multi engine CPL/IR and MCC and JOC training and it cost in full (this may have gone up slightly in the past 2 years) £67,500, this is pretty much the same for all integrated training courses at the 3 main treaining schools in the UK: OAA, Cabair and CTC (plus many i havnt mentioned) i dont know your finantial circumstances but i was able to fund the majority with a personal loan (bear in mind this was 2 years ago: pre recession).
The age factor does not exist as there was a 40 year old and a 36 year old on my course and not to sugarcoat it, no ones getting any younger; if you REALLY want to do it... then lets face it youll do it sooner or later, might as well be sooner.
Now as you know the industry is looking bad at the moment but the recovery has started on a minor scale in that some of the guys from my course have already got jobs, it may take a year or more to really recover but that means that if you start now youll be right in the middle of a period of growth when you finish in 16 months!
Hopefully this can help you get started, ive covered integrated training in the UK, now you just need to cover modular style training in the UK, then the rest of the world... :P but theres plenty of people on this site, ask them
Hope i helped in some way, good luck with everything bud,
TK
