10-15 seconds animated ads clip to promote an app

Background information: I have an app developed in the area of organizing and planning. The ideal outcome is an animated short clip that tells a story how my app is beneficial for the user. It should illustrate certain characteristics like how the user can use the app and its distinct features, which have a positive impact on the user (time savings, being pro active, well-organized, positive energy). The clip shall be some kind of story telling with strong images (dynamic and informative). Ideally, it picks up certain characteristics directly from the user interface of my app (in some way). Also, create an image that fulfills the above requirements (quality design that conveys a convincing message of the benefits of my app, here the design, authenticity, professionalism and eye for detail is of the essence). All above is needed to promote the app (therefore design and professionalism is key) Project worth is 90% short video clip and 10% an image (to fully convey message maybe 2-3 images are needed). I am away until 21.07.2020, after that i can concentrate more on it. Until then feel free to send me reference work and what you think may be a good idea. Thanks!
