Part-time nanny needed for 7-month-old in north county Cork

We're an American/French family searching for a babysitter/part-time nanny to look after our 7-month-old son in our home beginning early February, and lasting until at least July (preferably until September). We're located in a lovely rural setting about 10 minutes outside Watergrasshill, and have a huge garden to play in and plenty of space indoors as well. Ideally we're looking for someone 5 days per week for 3-4 hours in the afternoon, to provide childcare coverage while I work from my home office, but the schedule could be flexible for the right person. This may suit a secondary school or university student who is free in the afternoons, someone who is looking for some extra cash, or even a parent who wants to bring their own baby with them. Someone with their own transportation would be our preference, although we are open to giving lifts from Rathcormac or WGH. We will require garda vetting and can arrange that on your behalf.
