My old PPL instructor works Hems with a civillian background and no IR.
I believe he had 2000+ single/instructing time, he did have a twin rating but little time on twins.
Probably at the right place right time.
However if i was Ex Mil cheif pilot looking for staff. I won't hesitate taking somone with lower total time but some twin time.
Best advice i could give is bite the bullet get yourself a Multi IR and tout yourself around onshore PT operators. Flying around england and seeing where your going in a twin is a bit of a luxury and thin on the ground.
