Excel Dashboards for Financial Tracking

I need an Excel expert who can turn raw transactional data into clear, decision-ready financial insights. The workbook will lean heavily on pivot tables so I can slice results by period, account and cost centre without touching the source sheet. On top of that, I want polished line and bar charts embedded in an interactive dashboard that updates automatically whenever new rows are added.

Here is what I expect to receive:
• A single, well-structured .xlsx file with all calculations, pivot tables and visuals in place
• A dashboard sheet that combines line and bar charts, key metrics, and simple filters for date and category selection
• Clean, commented formulas so I can follow the logic and extend it later

I will supply sample data right after kick-off; please design with scalability in mind (roughly 50 000 rows per month). Let me know your typical turnaround time and one similar project you’ve completed so I can gauge fit.
