I am looking for a talented graphic designer to create a modern logo and additional graphical material for a new brand. The logo should be modern in style and will be used for branding purposes. Additionally, I require the designer to create additional materials such as graphics that can be used on LinkedIn. This will help create a strong visual presence to support the brand. The successful applicant must be creative and have excellent understanding of colour theory and typography to create a logo that fits with the overall brand ethos and identity. They must also have experience in creating graphical materials for social media platforms. Experience in creating effective visual content is a plus.
