Both my recommendations are in Greece, Egnatia and Global. Expect to spend around €10K on the CPL/IR conversion. What sort of MCC/JOC I would suggest depends on your experience, budget and aspirations. They start at about €2K and go up to around €14K. You need to do an approved ATPL theory course and pass all 14 ATPL exams prior to flight tests, but I assume you know that.
