I think almost any print shop should be able to handle that nowadays. There is at least one in every district. Some of the places look grotty on the inside, but they spend the money on machines, not decor.
Getting them to do what you want is easy. I wanted something done that was more complicated. By pointing, using my poor Chinese and using a translation app on my phone, we got it done.
Use any translation app to print out a note of what you want done. Avoid modal verbs, just keep it to simple instructions.
E.G. Print this in color, A4, all pages, one copy. How much money?
Take your document in on a memory stick. They will do the rest.
If they are trying to ask you things, give them your phone with a translation app open, they should know you want them to use the app.
Yes it does sound a little like there may have been pre-sales. A lot of the property may have already been disposed of in sales centers in Tier One cities. But that is speculation on my part.
As for the rich only wanting villas, most of the lower rich (not super rich) that I have come into contact with have a villa for the weekend and an apartment downtown for work. A few have multiple properties.
There are also companies that are cash rich, and with low bank interest rates, and little movement in the stock markets, that are still tying up cash in property.
