If you already have a CPL but want to be sponsored towards the IR you may well be listened to a bit more if you suggested you would be willing to sign on for at least 5-6 years.
If getting a twin with IR rating sponsorship means signing up for 5 years, then where do I have to sign.
You spent 50K just getting a JAA CPL?! I hope that includes living/transport/rent etc. If not, you were ripped off.
£50K is the going rate for a Integrated ATPL-H, you won't find an ab-initio course for much less in the UK. Come to think of it there are only a few FTO offering an integrated ATPL course for helicopters and I'm at one of them!
