I’m not able to help directly, but if your really stuck and can’t get someone immediately would you consider ringing your local county childcare committees, one in meath (046-9073010) and louth (041 685 9912). They have list of childminders in your area who might be available to childmind immediately and would probably work out more economical than you having to pay someone to work in your home.
Many people aren’t aware there is a big difference in bringing children to a childminder who works from home and bringing someone into your home to work. Childminders work from their own homes and are self employed, setting own rates and responsible for own prsi or tax if applicable. If you take someone into your home to work as a childcare worker then you become their employer and are responsible for paying their tax, prsi etc.etc.
Sorry cant help more but good luck with your seach.
