Design a Minimalist Digital Undated Planner-Calendar Integration

I am a proven e-commerce seller looking to create a high-quality, digital undated planner designed to seamlessly integrate with Google Calendar and Apple Calendar. The planner should be thoughtfully organized into weekly, daily, and monthly layouts, ensuring a functional and intuitive experience for users. I want the design to have a minimalist aesthetic that appeals to a broad audience, focusing on clean lines and simplicity. The ideal candidate must be proficient in platforms such as Canva, Adobe InDesign, or other tools commonly used for eBook and digital design projects. Applicants must provide references or a portfolio showcasing previous work, particularly on similar projects. The project must be completed within one week, so efficiency and attention to detail are essential.
