Opening a caravan site

How easy or difficult would it be to start a new business for a caravan site after I've bought a large house with land?
It will be complicated. If you are friendly with the Mayor I would start there. And the neighbors. If they are supportive it will be easier. 
Hullo Taylor, 
Where in france are you located? I am searching for a place to settle. I will be happy to help in your business as a volunteer not for money. I was formerly a professor (computer science) but am keen to settle in france. I like the concept of living in a caravan as I am single and i like to travel. Regards, Siva
