Dirt bagging around France

At the end of april I will be travelling from the UK to France for a month. I have barely enough money to feed my self on this trip so i will be getting around by hitchhiking and i will be sleeping in the dirt. My big destinations will (hopefully) be Font, Verdon, Chamonix and Ceus. I'm really just looking for lifts and a partner. If any body could help me out i would really appreciate it.
