Advanced Excel Forecasting & Presentation

I need a highly complex, multi-component business forecasting project involving advanced Excel calculations, statistical analysis, PowerPoint presentations, video presentation preparation, and critical evaluation. My objective is ensuring every component to be completed to an exceptionally high standard, strictly following the requirements and marking criteria outlined in the PDF that will given to you.
The project consists of four interconnected sections: Section A (20 marks) involves accurate Excel forecasting calculations using simple and multiple linear regression, seasonal dummy variables, and statistical analysis. Section B (60 marks) requires a professional PowerPoint presentation and a 5–8-minute video covering a step-by-step Excel regression demonstration, forecast analysis, diagnostic testing, identification of issues, critical evaluation, comparison of forecasting models, and justified business recommendations. Section C (20 marks) involves an additional 2-minute reflection addressing challenges, AI applications, digital literacy, and technical and professional skills. Section D requires a complete, well-organised Excel workbook containing all calculations, regression outputs, forecasts, and graphs, ensuring consistency across all sections.
Importantly, I will personally film, present, and edit the video, so I also require a complete, professionally written, slide-by-slide presentation script that aligns precisely with the PowerPoint and Excel work. The script should clearly explain what I need to say, when to transition between slides, which Excel calculations to demonstrate, and how to interpret and critically discuss the results. I would also like clear recording instructions and suggested timings to ensure the presentation is natural, confident, academically strong, and within the required time limits. The reflection section should include guidance that I can personalise to accurately represent my own experience.
My expectations are extremely high. Every component must demonstrate exceptional accuracy, sophisticated critical thinking, strong statistical interpretation, insightful business recommendations, and professional presentation quality. Please carefully review the entire attached PDF, particularly the High Distinction marking criteria, and ensure that all deliverables are thoroughly prepared, interconnected, and consistent. My priority is achieving HD-level quality across every section, with no missing requirements, calculation errors, weak analysis, or avoidable loss of marks.
