Hi dburan,
You haven't said what your experience/qualifications are.
If you only require 2 years for your Cat A have you already completed the required exams?
If the answer is 'No', and you are starting afresh, then why not shoot for your Cat B?
There are also places which are A LOT cheaper to live than Dublin.
Ryanair's provider in PIK will have much cheaper living costs than Dublin and can also offer all the relative experience required.
