Since you're claim to be legit a investor, I'm going to help you setting the deal.
Seems that the main problem is trust, so I think there is a way to solve this problem:
An air ticket from JFK airport to HK airport costs around 2K USD. The hotel cost is around 150USD/night, but let's have a blast and go for a fancy one with 300USD/night (Conrad Hong Kong) so, for one week, so you get plenty of rest, it's 2.1k USD. Now, let's add some costs for gourmet food, transport and gifts, let's say, 6k USD.

So, here you go, you can have a nice time on Hong Kong AND the chance to close a 3.75 million USD (with a profit of around 3 million USD, when removing shipping costs, travel costs, storage and so on)

Worst case scenario you have a nice 1 week getaway.
Any serious investor would have that kind of money, as shipping costs itself would be around 100k. 10k is nothing and if you have any problem, you can always cut the luxuries, that would make the travel roughly 4k.

Btw, you can schedule a meeting with GES HK using their e-mail.
Have a nice trip!
