I need an expert to develop a multi-level interactive Microsof Excel Gantt chart for a portfolio of 10+ projects

Required features of the Gantt chart: Project Information: Each project will have a dedicated row containing the project name, start date, end date, and key milestones. This information will be visually represented on the Gantt chart. Team Members: The Gantt chart will provide separate columns for the overall coordinator, specialists responsible for individual tasks, and other team members. This will enable efficient tracking of project responsibilities and coordination. Graphs/Charts and Illustrations: The Gantt chart will incorporate dynamic graphs and charts that visually represent project progress, milestones achieved, resource allocation, and other key metrics. These visualizations will provide a clear overview of the project status. File hyperlink: Users will be able to hyper files directly to the Gantt chart for specific project outcomes or reports. This feature allows easy access to relevant documents, fostering collaboration and information sharing. Budget and Implementation Results: The Gantt chart will include a dedicated section for project budgets, enabling the linkage of budget allocations to specific implementation results and timeframes. This feature will facilitate effective financial tracking and analysis. Summary Reporting: The Gantt chart will generate automatic summaries of results on a monthly, half-yearly, yearly, and end-of-project basis for each individual project and the entire portfolio. These summaries will consolidate project data, providing key insights and facilitating decision-making. Formula-Based Updating: The Gantt chart will be equipped with state-of-the-art formulas that allow for seamless updating and correction of project information. This feature ensures data accuracy and maintains the integrity of the chart. Professional Presentation: The Gantt chart will have a visually appealing and professional layout. The Gantt chart will utilize conditional formatting, data validation, and chart formatting techniques to enhance usability and aesthetic appeal. Additionally, it will provide detailed instructions and user guides for smooth navigation and utilization of the chart. Project Timeline: The estimated project timeline is 3-7 days to develop and deliver the Excel-based Gantt chart. This timeline includes iterative feedback sessions to incorporate my inputs and ensure the chart meets my specific requirements.
