One of the best places to find leads for writing gigs is:
http://forums.writersweekly.com/viewforum.php?f=4
The owner of that site researches and calls around to find new gigs to
post each week and really puts a lot of effort into it. So much effort,
in fact, that others have come along and plaigarized directly from her
site, which is totally illegal, but some folks don't understand the
whole concept of copyright violation.
Great site, though, and she also has a weekly e-newsletter that's fabulous and a message forum for writers on her site.
