15 International Trade Articles

This project is for an international trade site, we require 15 well written articles of at least 500 words each. There is a very wide range of possible topics - starting an import/export company, import/export procedures, packing/shipping, product research, languages/customs/negotiating. But a couple of areas we'd like covered are trade shows and online b2b portals. We are very particular about language and grammar so would prefer Native English speakers. The articles should be original and well researched. Copyright will transfer to us on completion.
