Custom Excel Price List Design

I need a clean, well-structured Excel workbook that will serve as the official price list for my limousine services. The sheet must look polished enough to share with clients directly, so layout and visual design matter as much as the underlying formulas.

Here’s what I expect:
• A single-page overview that lists each limousine service, its base price, any optional add-ons, and automatically calculated totals (tax, gratuity, surcharges).
• Simple drop-downs or checkboxes that let me toggle extras on or off and instantly see the updated price.
• Attractive but business-appropriate formatting: company colours, styled headings, and clear separation between service tiers (e.g., hourly charter, airport transfer, wedding package).
• Built-in protection for the cells containing formulas so staff can edit prices without breaking anything.

Please build everything in standard Excel (.xlsx) so I can update it later without extra software. If you have experience designing client-facing price sheets—especially in the transport or hospitality space—let me see a sample. I’m ready to move quickly once I find the right fit.
