1.  I would want to have a ranking of the world?s most successful
children?s writers (top 20).
2.  Where do they live? 
3.  Out of this list - are there any who are committed Christians in
their private lives?
4.  Are there any who are known to have a special compassion for third
world poverty?

This looks to me as if it will be a great deal more work than most
Researchers are likely to want to undertake in order to earn $15 (the
Researcher's share of your fee). First we have to compile a list of
the 20 most successful children's authors in the world (how are we
defining success? By the number of books sold? By the author's wealth?
By the number of awards won?) Then we have to find each author's
address, and detailed biographical information regarding religious
beliefs and charitable interests for each of the twenty. I'd estimate
that this may be at least a four-hour project.
