Living in the French Riviera

Hello
Having worked on the Cote D'Azur years ago for several years, I have long harboured an ambition to return to live there permanently.  OF course we would need to make a living, and with my background in travel and tourism, this is a natural area for us to move into. We would love to be able to buy an established mobile home holiday business - if they ever come onto the open market! - but having made some enquiries, it appears that finance is not available through the usual channels for such a business as no real estate is involved. The only way I could envisage being able to do it, would be on a 'lease purchase' type agreeement - ie paying a lump sum to the owner at the end of each season for a set number of years until the business is bought.
Is there anyone out there with experience of buying such a business, and if so, how did you finance the operation? Secondly - does anyone want to sell their business?!
