Extra notes: Currently I have a logo which I made myself and d not like.
I need a logo that looks kid friendly, fresh, creative and professional. I really like the idea of trees to represent growth - children's mind growing.

I need the logo with original files and the names and fonts used.
Also need logo versions in different colours in case needed to use in different colour backgrounds.
Logo files include PNG
