Excel/Google Costing Estimation Spreadsheet

I’m looking for an experienced Excel or Google Sheets specialist to create a clear, reliable costing and estimation workbook that streamlines our quotation process. The workbook should include a structured background data centre for pricing, cost build-ups, and relevant calculations, alongside a clean, intuitive front sheet for entering project details and generating quotes. It should be easy to update, accurate, and simple for our team to use, with well-organised formulas and a professional layout. Please describe your relevant experience and how you would approach the project.
