Custom Home Interior Trim Estimating Spreadsheet

I have a working but rough home-trim estimate spreadsheet that needs to look and behave like a polished, client-ready tool. The first milestone is to tighten up the layout, add reliable cost-calculation logic, and set up input cells that start as simple manual entry yet are structured so they can be converted to drop-down selections later. Once that sheet is solid, I’d like to keep collaborating on additional spreadsheets—particularly a feasibility model for investment properties—so clean, well-documented formulas and modular design are essential. Deliverables for this kickoff: • Refined trim-estimator workbook with clear formatting, protected formulas, and dynamic cost calculations • Input framework ready for future drop-down implementation • Brief walkthrough notes or a screen-recording showing how the calculations are organized, so I can maintain or extend the file easily If you’re comfortable building Excel or Google Sheets models that balance usability and accuracy, I’m ready to get started right away and grow this into a long-term workflow.
