Tour guide south of France

I am looking for a knowledgeable and experienced tour guide to provide services in the south of France. Specifically, I require guided tours in both English and French to cover areas of Provence. Whilst conducting the tours, the guide would provide information about the attractions and destinations visited. The tour guide should be able to describe the historical and cultural subtext of sights and monuments, to let visitors appreciate their significance, as well as their aesthetic beauty. A passion for the region, as well as an enthusiasm for the job, should be evident in the language and delivery of the tours.
