Creative design for business presentation

I’m looking for help with the design element for business pitch document. Specifically I am looking for someone who can help create a unique design for my presentation. The design should be a PowerPoint Slides design, without relying on a pre-existing concept or design. My goal is to use the design to engage my audience and help make my presentation even more impactful. Whoever I work with should have an impressive portfolio of creative design work, and come up with fresh ideas to incorporate into the slides. I expect professionalism, communication and dedication to ensure a successful end product.
