Maybe I am misunderstanding you ... you want to find a UK or Irish flying school (because of your ATPL theory credits) that will let you have a CPL instructor and R22 for way under the going rate AND personally negotiate the right to train you overseas if necessary?
Remember an FTO approval for modular CPL does not come lightly or cheaply, let alone for overseas approval - we aren't talking RTF for PPL training. If it was that easy every school would be an FTO. Take it from me, getting modular CPL approval is
not an application form dropped around at the Belgrano with the approval mailed out the following week
I'm not quite sure of your last comment - many current and ex instructors dedicate quite a lot of time on here to help answer people's training questions, take our advice as you see fit.
