Hi there. To summarise the different routes -
Integrated Course - 195 hours flight time, around £50,000. Courses are generally scheduled to last around 13 months. Currently 4 schools approved to run the course are Cabair, OATS, BAe (Spain) and WMU (America).
The modular route - where the basics of the integrated course are split into 4 or 5 different modules - your PPL, Hour building, ATPL ground exams, CPL / Multi-engine Course and the Instrument Rating. Cost generally around £30,000. Doing it full time, you would expect to take just over a year. The advantage the modular route has is that you can just do each module a time, therefore meaning you don't have to give up work, move out of house etc.
It doesn't matter which route you go, you come out with a JAR Frozen ATPL. At 200 hours you are probably more likely to get a job if you have completed an integrated course rather than a modular course (in my opinion).
Of course once you've got your licence you can do one of 2 things - just keep applying for jobs whilst just doing enough flying to keep current, or work either as a flight instructor, glider towing etc. to build your hours up to the magic 1000 mark. Once you have got around 1000 hours (which would probably take you a little over a year) you would then find that it becomes a lot easier getting a job. If you have a thousand hours, I don't think airlines care which route you went.
