I have to agree with KIA, Hong Kong would be a very limited market, amongst a business population that won't care about your idea. USA, UK, Australia, NZ and the EU is where the talent is, and the specialisation.
Also consider that Hong Kong is socially about 15 - 25 years behind the rest of the world, they still buy Karen Carpenter greatest hits CD's, what does that tell you....
. In my opinion also, the way that business is done here, blind freddy could be a billionaire if the amount of insider / behind closed door activity that goes on here, and its far from the transparent market that so many people boast on about. Quiet a few area's of how business is done, would end you up in jail back home... Hong Kong loves its monopolies and Hong run cartels... Nothing is going to change, and unless you are geared toward a business that interests them, you will have buckleys and no hope getting venture capital raised. You'd have a simpler task raising capital to open a new start up airline, than what you're proposing lol...
USA is where I would be investing my time, I'd probably consider a US based institution over a HK one, if you plan to be accepted in the USA. Most Americans think Hong Kong is in Japan.... That may be a good, or could be a bad thing...
