You need to do a little bit of work
I looked at the CHC global vacancies, and for a touring pilot they want
Heavy types 3000 hours / 1500 PIC / 1200 multi / 300 offshore
Mediums. 2000 hours / 1000 PIC / 500 multi / 300 offshore
And at least 100 on the types global use i.e. S76, AS365, AS332, AW139, EC225, S92
So on the face of it you are well short here, I know you have 1000 hours, thing is in the civilian world, it's just not that much.
Co Pilot on SAR sounds more do able to me
