I am trying to plan a month full

I am trying to plan a month full immersion experience in Sicily's northeast corner, probably alone.  Either this fall or next spring.  I want to be in a town or at least close enough to walk to the town/village and be able to get to bus/train to go on tours around the rest of Sicily. I want to be able to buy local foods and cook myself.  I have also thought of doing a work/volunteer in trade for room and board.  But in a very clean, safe, nice place.  Maybe an agriturismo winery, orchard, olive farm?  I'm 66 years old but in good shape and young at heart.  Currently studying Italian and want to continue to learn over there. The place would have to be allergen/pet free/no smoking. My parents are from the Messina area.  I hear how beautiful Toarmina (a little pricey), Cefalu and Catania are.   I just need to know the best safest way to go about this. Any advice is welcome.
