The Crochet Guild of America (www dot crochet dot org ==> select "Resources" then "Crochet Left Hand") has a series of illustrations which may help. (I can't put the url directly in b/c of forum restrictions; ironically, I registered specifically to guide you to the illos! but am prohibited from posting links/urls until I've posted more messages. Oh, well....)
They're drawn specifically for left-handed crocheters. I know that there is at least one book on the market for left-handed crochet work but can't think of its name right now. Sorry; will post back when/if it comes to me!
