I agree with FM. Current on the 550 and a couple of hundred hours, go knock the doors of all the biz operators at Citygate, don't forget the mentioned Jet Aviation HK, Metrojet, HK Jets. There should be a reasonable chance for an FO position for the right guy.
Not particular hectic, with an average flying of about 250+\- hours a year. Basically always on standby. Pretty good pay and housing. Hong Kong is great place for a periode of time, doesnt have to be forever.
Good luck
