Caravan Repairs in France

My Bailey Buccaneer recently sustained damage to the rear near side panel and awning rail whilst stored on a site in France. My insurance company want me to recommend a caravan repair workshop or company in France capable of major exterbal apnel reapirs; at present I cannot locate one at all. The caravan is located in the Loire Region. I would be grateful if anybody has had the misfortune to require a similiar repair in France.
