market business enquiry - another one!!

[clc]

Having seen the posting for small market business, I was just wondering if anyone knew how to go about getting any information on the subject. I speak fluent french so a french site is not a worry. I am interested in setting up a small business,touring the local markets. I have just arrived in the 56 having been living in the 35 and 53 for 5 years. I am currently hoping for a teaching contract in a local school (waiting on confirmation of placement) Is it the "marie" you need to go for permission or request of a plot? Is there a necessary "formation?" Any advice appreciated. Here's hoping and probably dreaming - but I am serious.
