English childcare (Alicante)

Hi I am looking for advice on the childcare situation in Alicante with regards to children under 3.
I understand children start school at 3 in Spain and before that i suppose they use a nursery - here in the UK I am a childminder and we are looking to move to spain however I am nervous that my business wouldn't be something there would be much need for in spain. Im inspected the same as schools and nursery and hold an outstanding grade the highest available and would love to carry on caring for children when we move so am looking for any advice especially as I do not yet speak any spanish !! Many Thanks
