Ask HN: How could one enter the business of imports/exports?

Hey guys I'm very interested in this field and I am fluent in several languages that are very central to a lot of import/export hubs.I'm very interested in the business and was wondering where I could start with this. I just want to export/import large amounts of whole sale products.

Are there any sites that I should check out in particular?

Also is there any sort of website that hosts a lot of Chinese manufactures? How do I get in touch with them?
