Municipal Rate Excel Estimate

I need a clean, fully-formulated cost estimate laid out exactly in line with our municipal Schedule of Rates. The final file must be an editable Excel workbook that mirrors the official column order, item codes and measurement units so it can be dropped straight into the approval process without extra rework.

Here is what I will provide once we start:
• The list of work items and their respective quantities.
• Any special notes or local amendments to the latest municipal SoR.

What I expect back:
• One Excel file with separate sheets for summary, detailed rate analysis and contingencies.
• All rate entries pulled directly from the current municipal SoR, with formulas intact for easy updates.
• Grand totals, taxes and overheads calculated automatically.

Please highlight your direct experience preparing government or municipal estimates. A quick example screen-shot or reference project will help me understand your familiarity with SoR compliance and Excel automation.
