Thanks very much for the advice, MasterQ, Dave, Dave, Ted, Willy and Danny.
The job is tantalising close, but possibly no cigar.
The school like me, my experience and qualifications are fine and a good fit for them. The job is in a really nice park, Sai Kung Country Park. I spoke to a really nice guy who works in recruitment, who told me about accommodation and stuff. He said that because it is away from the main island, prices were reasonable by comparison. £700-900 pcm for a nice apartment.
The catch? Well the Hong Kong qualifications authority have some ridiculously specific requirements. They want a BEd in Early Childhood Education. I have a BA in Film, a postgraduate teaching certificate in Early Childhood Education, plus I am studying for an MEd, plus I have 17 years teaching young children. Anywhere in England that would be recognized as more than equivalent. Not in Hong Kong. There may be grounds for appeal, but they are not that flexible and take weeks to come to a decision. The school think I am a good fit, and want me to come over and see, get a teaching job until they come to a decision, but that only pays about £20000, not really feasible.
The guy was very friendly, and, even though it's not in his interest, suggested I try some other schools for teaching jobs, which might be recruiting soon, and pay quite a bit more.
So, I am surfing the Hong Kong education sites for some info.
My lady was ecstatic when I told her I was applying this morning on the webcam. I hope she takes it OK, if I don't get a job. Maybe I shouldn't have told her. Oh well
