Hi, can anyone help - i am moving to campoamor on the Costa Blanca in the spring and am hoping to set up a childminding business. I have qualification and experience and got a clear criminal record check. I have been told that there should be a call for childminding especially in the holidays and after school hours, however i have been investigating the nurseries and they take children/babies of all ages and are extrememly cheap! Can anyone advise if i have to become registered like in the UK or even if childminders exist in spain......What would be the best way to advertise out there too??
Thanks.
