Hi James,
I've recently spoke with an agency from HK got his contacts from Facebook group "Incorporate in Hong Kong" or something like that.
I have already exchanged few emails with them and I'm waiting for a phone call now to discuss more details.
I've seen that they make appointment to more than just one HK︀ bank and even though you'll get rejected by some, people are still reporting that they︁ get accepted by some.
Please keep us posted.
