The logo should emphasize the following: 
 
Happy Children with Chess (preferably 1 Boy and 1 Girl) 
Global 
Name Organization: Child&amp;Chess 
Subtitle: Bringing Happiness and Peace 
Main housestyle colors: Orange #FF6600, Black #111111 
 
It should be a professional logo, to be used to get sponsors from big companies. 
 
I like the Unicef logo a lot. Maybe that can inspire you.

Megalogos is an exceptional good logo designer! And the service is excellent. Very fast response, high quality logos. 
For me Megalogos is the best!
