You could theoretically go to somewhere like Aerofan in Spain and do the IR(A) in a relatively short period of time on a single engine plane for about 6000€, then come back and do a type rating for as355 and then the 10hr conversion for ME IR(H). It might save you some money and you would then also have a fixed wing IR too. Only real decision is do you want to do the majority in a box-like simulator or in a real aircraft? Of course, cost comes into it but Aerofan reckon on 3weeks for a SE IR(A) and I don't believe it can be done in that short a space of time.
