Hello Miriam, Mary Carroll Moore is a published author, presenter, etc...she shares a lot of information for free via her weekly newsletter and from her website...she might be a good resource to look for ideas on publishing, finding an agent, self-publishing, etc.
http://www.marycarrollmoore.com/ Her weekly newsletter is well worth subscribing to...and she is down to earth...I've attended workshops of hers that have been very helpful.
Take care, Michael
