A detailed document outlining the project's objectives, scope, timelines, and costs. This will include a clear description of the your requirements, a proposed solution, the technologies going to be used, and the overall project plan. This helps set expectations and serves as a reference point throughout the project.

Present visual representations of the website's layout and design using wireframes and mockups. These can be low-fidelity wireframes initially to demonstrate the site's structure and functionality, followed by high-fidelity mockups that showcase the actual design, color scheme, typography, and imagery. This will help visualize the end product.

Develop an interactive prototype of the website that allows the client to experience how the user interface and navigation will work. This can be done using tools like Adobe XD or Figma. A prototype will help understand the user flow and make any necessary adjustments before moving to the development phase.
