Malc,
I'd hold off on that cheque. It looks like you've not done your research to any level of depth. If you select the integrated route, then Oxford will charge you 72K for around 200 hrs of flying, your ATPLs, IR and JOC/MCC. It's a significant amount of money to spend for what can be done for less by completing the modular route:
PPL/Night = 5K
Hour Building 100 hrs - 6K (in the US)
ATPLs = 5K
CPL/IR = 12K
Multi = 5K
JOC/MCC = 4K
Accom for the year, 6K
Total = 43K + 3K for exams =46K (you might want to add contigency of 10-15%)
Now, you got that extra dosh to:
Flight Instructor Rating = 6K
OR, even a Type Rating = 25K + 46K = 71K
Which at the end of the time, might get you 200 hrs on piston with 100 hrs 737 (using Astreaus). And, you've still got the same licence, but with line experience!!
I reckon its worth you finding out some more details before you post the cheque.
