I don't think the building of a liquid Nitrogen plant is a job for the amateur, If you only want a small quantity it is far better to buy it but if you need lots there are industrial plants on the market such as below.

Only communists say that.

Are you a commie? No?

Then stop ruining it for the rest of us and vote!

The poll makes no sense, but people seem to like voting anyway.
I think that what you need to make liquid nitrogen is money.
