Sorry if I misunderstood your question...
You need Software to create flash movies??

If that's the case, there are 3 that I can recommend:

Begginers: SwishMax
Developers & animators: Flash MX 2004 Pro
Animators: Moho

this are the main programs I use.
the first one, let's you make text animations and transitions in a very easy way.

the last two are more advanced but great. :)
