Camping Uk

I would really like to work abroad next summer, either in France, Germany or Switzerland, and wondered if anyone can give me any tips on getting a job for a few weeks. I would like to work for a campsite abroad, or a holiday camp, but the ones I have seen advertised want you to commit to a 6 month period. 2 months would be ideal for me - anyone know how I go about this? I speak average French and near fluent German. Thanks
