Jersey Aero Club 45 hour PPL Course including equipment/tutorials/radio telepphony test/all ground exams/final skill test (no extra landing fee cost) £5665.00
I know this is probably no good to you, but if you could take 4/5 weeks off work, you get class A and class D airspace under your belt and awesome cross country experience to France/UK/Guernsey/Alderney.
JAC also organise great rates at a local guest house, so all in would still be cheaper than the UK.
(£11k sounds painfully steep)
Just a quick note, I thoroughly recommend IMC rating as well as PPL as it does sharpen your skills considerably.
