Irish family looking for child minding advice

[Irishvisitors]

Hi, I'd be very grateful if someone could point me in the right direction! My husband is working in Singapore from the 14-25 February and our three boys (6, 4 and 4 years) and I are travelling with him. I would love to find someone who could help me with the boys during the day and possibly some babysitting in the evenings. Where would be a good place to find someone who has experience and references and what should I expect to pay? I know I have left this very late to organise as we were moving house but really hoping I can find someone who could give me a hand! Thanks in advance. Colleen
