Design a Marketing Campaign for an Application

I need an experienced Graphic Designer to design an application company's artworks for the upcoming media campaign. The media campaign's artworks will consist of 2 animated social media posts, 2 fifteen second ads for digital signages, 1 animated YouTube tutorial video and 1 A5 flyer (back and front). I am looking for a designer that is able to grasp our existing design standards and blend them seamlessly with their skillset.
