France - workers to improve my property

Hi I am Engish/Irish and from England, my name is Kevin. I have a property in France at Mansle which is in between Poitiers and Angouleme in the Poitou/Charente region of France. I would like to offer free accomodation, less commodity bills i.e. water and electricity ect., and local taxes, in return for 1.5 days per week work to improve my property. The accomodation is a little sparse but accomodating and would offer the oportunity to become established. A permit to work is a French requirement and I'm not sure how easy that is to obtain. Mansle itself is mainly agricultural. Angouleme and Poitiers offera much wider diversity of employment.
I do not know of any Polish communities in the area.
