Google Sheets & Excel Developer – Create 8 "100x Masterpiece" Digital Products for Etsy Shop

I am building a premium digital product store on Etsy called PlanYourLifeWell. We produce top-tier Google Sheets and Excel financial, business, and productivity spreadsheets. Our main competitor benchmark is PrioriDigitalStudio on Etsy. They have over 140,000 sales because their sheets are clean, but I want to build a collection of 8 Hero Products that are 100x better in design, usability, automation, and video marketing. What "100x Masterpiece" Means For This Job: Modern App-Like UI: Hide standard gridlines, build rounded container blocks, and use a custom sidebar/header navigation menu so users never have to click bottom Excel tabs. Tranquil Color Palette: Muted, elegant color schemes (Soft Sage, Taupe, Slate Dark Mode, Warm Neutrals). No raw/default Excel greens or blues. Smart Automation: One-click script buttons (e.g., reset sheet, add row), dynamic progress meters (SPARKLINE), and auto-sorting formulas. Dual Platform: Every product must work flawlessly in both Google Sheets and Microsoft Excel (.xlsx). Bulletproof Protection: All formula cells must be locked with protected ranges so customers cannot accidentally delete or break them. High-Converting Video Assets (MANDATORY): For every single product, you will also create: 1x Etsy Listing Video: 10–15 seconds, 1:1 square or 4:5 vertical, high-resolution (1080p), showing real-time sheet interaction (entering numbers, automated charts moving). Must play smoothly without sound. 1x Social Media Ad Reel: 15–30 seconds, 9:16 vertical (1080x1920) for TikTok/Instagram Reels/Pinterest Ads, featuring trending text overlays, clean transitions, and engaging background music highlighting the problem the sheet solves. The 8 Hero Products to Build: Ultimate Annual Budget Spreadsheet (Multi-tab suite) Paycheck Budget Planner (Biweekly/Weekly cash flow) Small Business Bookkeeping & Inventory Hub Debt Payoff Tracker (Snowball vs. Avalanche with visual progress bars) Yearly Habit & Routine Tracker (ADHD-friendly with gamified streaks) Project Management System (Dynamic Gantt Chart & Kanban Board) Wedding Planner & Budget Spreadsheet All-in-One Life Planner (Dark & Light Mode) Screening Questions (Required to answer when applying): Please share links to 2-3 Google Sheets or Excel templates you built specifically for digital product shops, PLUS links/samples of video ads or listing previews you created for them. How do you implement global navigation inside Google Sheets so users can jump between tabs easily? Type "TRANQUIL" at the top of your proposal so I know you read the whole post.
