If your going into the website makeing area, its best not to use others stuff. You'd never learn anything, and its just a rip of their idea.Yes Flash can be one mean mofo to start out with,but everything good takes time to lear how to use.
You shoud first lean Swish 2, then move on to Flash MX 2004 when you feel ready. Swish 2 is very easy. But you can only do so much with it.
But if you look over google.com for "free flash intros" you'lll find them.The free ones are not good though.You'll need to pay for the good ones.
Template Monster has what your prob looking for.They have alot of templates and flash's.
