If you google "acheter un conteneur", you'll get plenty of company names. But, as Google gives different answers to different users, here is a short list:

And classified ad websites might be a good idea too, if you know what you are doing.
I looked into it, a couple of years ago and it turned out to be rather expensive. But it depends on the need you have of it. Anyway, be prepared to pay the delivery charges for a lorry and a crane. And there is also some earthwork to be foreseen.
