Hello Kangeroo and Vendeene,
I teach in France and have been doing so for a long time now. I teach adults and children. Sometimes I have requests for business English private courses and I also teach Business English directly to companies as I am a certified "Centre de Formation".
You don't specfiy what type of business your students are in. You may find resources for different types of Business English are easier to find than others. For instance, if you are teaching English to tourist office personnel or ski teachers, there are loads of resources out there.
Generally speaking though, I have found the Penguin English Photocopiables to be great for pair work and communicative activities. There are 2 of them and there is also one called Business English Meetings. They have nothing to do with writing up a needs analysis or a curriculum for your course but they offer some good ideas for activities to keep your class alive. If you want more information on how to determine exactly what your students need in the way of listening, speaking, reading and writing skills have a look at an article I have written on Teaching Business English: A Needs Analysis at the following link:http://www.suite101.com/content/teachin ... is-a226062
Hope this helps!
