Advertising yourself or putting it about by word of mouth, that you're available to run errands for housebound people, writing to local garages and small businesses, offering to be their "tea person" or to tidy up, car washing, gardening.
for the love of god, do not use connections - they dont know a thing. local papers are good, or the post office should help as they advertise jobs in the windows. Have you tried helping at a home for the elderly? Or even a local hotel, they need staff in on summers as they get packed and its good money :)
