Andrew,
Whether you do intergrated or modular your only going to come out with the same rough hours of around 200-250hrs. Nobody expects you to pay for 750hours by yourself.
Many integrated students still go without jobs for ages, or will have to go down the instruction or self type rating funding route like many modular students. Of the numbers of people who do intergrated courses only 50% get put forward and only 25% will normally get direct placements tops from the likes of Cabair or OAT.
With everything in aviation its who you know and when and where you apply.
Talking of time limits, theres very little difference. Your talking 18months for an intergrated course, and as long as your fairly full time at modular it doesnt take much longer to do it. For example with myself, i will be working here and there to fund the course as i go along. Forgetting about my PPL, from the date i started my hour building up to being full qualified (PPL, Night, MER, CPL, IR, MCC) im looking at roughly one year, give or take, add to this the couple of months it took me to do my PPL and night rating etc, were not talking much over 18months, so not too far off intergrated route. Add to it another month to do an instructors rating its not bad going.
For me i will be fully qualified at 20, so it wont be the end of the world if i end up instructing for a few years, as i will still be under say 25, so im not in a real rush for an airline job (although it would be nice) once ive qualified. For you it may be different.
