In my opinion you have a high chance of landing an airline job within 6 months of completing an integrated course at the likes of Cabair, Oxford etc. You just have to remember it's not guaranteed, unless you are on a mentored scheme of some sort, which even then is still not 100% guaranteed.
I am assuming you want to go integrated and not modular due to the timescales you mentioned. Which is better is another argument altogether and a search of this site will reveal endless threads on modular vs integrated. It's always a touchy subject but I believe integrated courses offer airlines more of what they are looking for, and with the possibility of tailoring these courses to include company SOPs (as in mentored courses) you get a pilot who is a ready as he or she will ever be for line training when they finish the course.
Modular is a hell of a lot cheaper though.
You pays your money and you makes your choice.
