Create a realistic and visually appealing cover for an online course module on "Guiding the Client: Step-by-Step for a Secure Purchase." The cover should feature a high-quality, photo-realistic image that represents a team of loan officers guiding a client through the mortgage process. Design the image to show a visual path or roadmap with distinct stages, each representing key steps like property consultations, signing contracts, and finalizing deals. Include interconnected milestones along the path, visually showing the support of the loan officers. Use a sophisticated color palette with dark blue (Navy Blue), white, and gold. The style should be clean, professional, and minimalistic, with the loan officers and the guidance process as the focal point. --ar 16:9  --s 750
