Hi,
I would be happy to undertake this task for you, I work daily with excel producing reports with big data sets and incorporating dashboards and charts to make the information manageable for stakeholders to gain an overall understanding quickly of what the data is showing.
I am more than happy to discuss any further requirements for this role and outline how I would manage the project, all my sheets come with a summary / dashboard sheet to show the data quickly and also a instructions sheet which details how the data is pulling together so you can better understand and present data analysis.
Kind Regards
Rob
