I want to know how to find the right person to look at my four
children's stories recently written with a
view to eventual publication.

You might find it useful to consult some of the perennial reference
books on the subject such as "2006 CHILDREN'S WRITERS & ILLUSTRATORS
MARKET" edited by Alice Pope or "BOOK MARKETS FOR CHILDREN'S WRITERS
2006" by Marni McNiff.

These references (or other like them) should be available to you from
your favorite bookstore, online bookseller, or library, and should
give you some insight into how the world of children's publishing
works.

I recommend The Writer's Guide to Book Editors, Publishers, and
Literary Agents, because (unlike other books) it not only names
editors and what subject matter they focus on, it often gives more
in-depth info on them that can be useful in crafting query letters.
Always, however, be sure to call the publishing house and ask if the
editor is still working with the company.

If I were you i would take a look at som children's books simmilar,
but not the same as yours.  If a publisher is already running a
serries very much like your own, they probably will not be interested.
 Also look at the format of books the publisher works with.  Most
children's books are 16 or 36 pages, (The printing machienes are made
this way,) If your book isn't something that they can print, they
wont. SOmething that might help is to suggest you are willing to help
promote your book.(visit schools, libraries, book signings).
The writter's market is a great sourse for a list of publishers, i
would start with it.  If all else fails, try printing at a local press
with a one year contract, and REALLY promote locally, or print it
yourself with a print on demand shop (google print on demand for a
list) it really isn't that expensive, and you only have to sell 1000
copies to become a best seller, then the publishers will be happy to
talk to you.  (Public schools average 600 kids, whose parents will
usually give them a few dollars for 'school things" like this, just
don't try to get rich off these initial sales---wait till you are
really published.
I hope this helps
