Create a realistic, high-quality image for an online course module on "Guiding the Client: Step-by-Step for a Secure Purchase." The image should subtly represent the idea of guiding clients through the real estate process, featuring a modern office environment where real estate professionals assist clients. Show elements like a roadmap or path leading through different steps, such as property consultations, document signings, and handing over keys, all without a background (transparent or plain) to allow easy integration into a layered design. The image should focus on professionalism, with sleek interiors, clean lines, and a minimalist yet elegant style, emphasizing trust and guidance. Use a sophisticated color palette with dark blue (Navy Blue), white, and gold.  --s 750 --no background --ar 16:9
