Create a 1,5 to 2-minute animated video directionally somewhat similar to this one: [login to view URL] or this one: [login to view URL]; we are interested in suggestions for how to render our story. Script/narrative is written. Designers interested in this project will be sent the script, we cannot publish it on the site. We will provide directions for style of graphics, based on existing graphics portfolio. VWe will publish the video ourselves. VO optional, we have in-house talent and would simply be looking for you to merge the audio file; however, if reasonable, we'll entertain quotes for VO.
