I'd be brutally honest with you - you sound really confused indeed. And trying to jump into helicopters just because CX has dumped you is like jumping from the wok into the burning fire. Don't do it ! The grass always appear greener on the other side of the fence until you get to the other side, and besides, helicopter training is far more expensive than fixed wing.
Don't think of HK as your first stop. It will become your crowning glory later down the line if you work hard enough. There is no GA in HK as a stepping stone so don't train in HK (I don't call Day VFR circuits in a single engined aeroplane "GA"). Go and get a JAR/ICAO/FAA CPL licence and build a couple of thousand quality flying hours after your MECIR (and by that I don't mean just Day VFR circuits in a single) before even contemplating a place like HK. Go where the jobs take you; you don't pick the geographical location. That's the nature of the industry.
Your primary problem appears to be financing. USA is just about the cheapest place on earth for flight training and if you can't afford it now, earn some money doing something else before commencing your flight training.
