Educational Boardgame Inquiry from Hong Kong

I have an enquiry regarding the printing of an educational boardgame that I have developed.
I will distribute it in my home country, South Africa, but I live in HK so am looking at options for printing here.
A few questions:
1. What is the minimum amount of units that you print?
2. Is there a specific size board or box that you have a template for, that will bring down the cost of printing if it is used?
3. Can you give an estimate of the cost of printing for a game consisting of a rectangular board with blocks on it (no pictures), about 350 small playing cards, the box, a dice, and a one minute sand timer? I know it is quite difficult to do so it you haven’t seen what I have in mind… let me know if you want more information.
