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 in a modern office setting, guiding a client through the mortgage process. Show a clear and practical visual path or roadmap, with key steps like property consultations, document signing, and receiving keys, represented by real-world scenes. Use realistic, professional elements like desks, computers, paperwork, and relaxed but focused interactions between the loan officers and the client. The color palette should focus on dark blue (Navy Blue), white, and gold. Keep the style grounded in reality, professional, and minimalistic, with the loan officers and client interactions as the focal point. --ar 16:9  --s 750
