Visual Design Overhaul for our Company/Brand

Hi, I work for a company in Sweden that currently is looking for a freelance graphics designer. If it works out nicely we will probably have more work coming up in the future. We have come to a stage where we need to find a consistent visual design to all of our content on all platforms where we currently are present. For this we would like someone to create easy-to-use templates (Illustrator/Photoshop/Affinity Designer/Photo) that we can use to create: - Visually appealing social media feeds (Posts and stories for Instagram, Facebook, LinkedIn and so on) - Header images both for our web page and for Facebook, Youtube and similar - all with the same look and feel. - Powerpoint presentations and press releases Keywords for the design are: Trust - Confidence and Professionalism We also want the design to have a modern and clean look. (See images named "main_inspiration") When it comes to social media posts, we will have a few different reoccurring categories/topics that the posts will cycle through. Each topic will need a slightly different recognizable look. (See images named "Instagram") We also want the visual design of the Instagram feed to create a nice puzzle-design (For example: Every third images have the same category and are connected visually thanks to template). The categories/topics are (but may be change): "Educational", "Customer cases", "Inspirational", "Product Information". I've provided some images to help understand the look we're after. - The images named main_inspiration have the right colors and feel. - The images with "Instagram" in the name are drafts/inspirations for how we would like the Instagram-puzzle to work/look like. These are just drafts however, so if you can develop these into something much nicer that would be great. We already have a logo (the one you see in some of the images) and this will be provided later on to the one who gets the job. Thanks for now and I hope to hear from you soon! Best regards /Samuel
