Translation for meeting on 18 Jan

We are a climate action charity (http://www.wearepossible.org). We are working on a project with partners in New York and in Paris. Our Parisian partner is not bi-lingual. We have a meeting on Monday 18th January from 16:00 - 17:30 (GMT). I am looking for someone who will be able to translate the English to French, and the French to English. There will be 6 people on the call.

Many thanks,
Hirra
