Blog posts for a language school (in French)

I'm looking for interesting posts that combine the learning of the English language with business. It need to be targeted to an an English learner, so really focused on the language - not only the business skill. Topics can include : Dealing with an angry customer in English, How to sound more diplomatic, How to say NO to a customer....really focused on the linguistic aspect but in a business setting. I'm looking to work regularly with someone - so if I'm satisfied with the work it will be a recurring job.
