How to apply for a day care centre?

I will be transfered to Helsinki by my company at October and now i am a mun of 13. I need to take my boy with me, i don't want to leave him in China. My company's working hour is from 9:00AM to 7:30PM. I searched that most of the day care centre closd before 5:00PM , some even colsed at 4:00PM . So How can i solve the problem that there is no person could help me to take care my son after the day care centre closed? Thanks everyone. I am still in china and i haven't been to Filand, i don't have enough information to solve this problem.
