Online Flash Intro Creator

I need a WYSIWYG flash animation editor for a web site. Please look at [login to view URL] to see an example of what I am looking for. I would like an exact duplicate or improvement upon their design tool. The editor should be able to create multiples scenes, which could include images, text, sound, and basic effects. The final movie will then be rendered to a .swf file. Preset animation effects will need to be available for the text and images. 8-10 effects should be able to be applied to the text/image such as a fading effect etc. If you have ideas for improving or adding to the design tool on [login to view URL], I would like to hear them. Please indicate whether these additions are included in your bid or how much the addition would cost. Please only submit a bid if you can create a design tool which is as good or better than that available on www.flashberry.com.
