Shopify Bakery Pickup Ordering Site

I need a Shopify storefront that lets my customers order our signature cakes and cupcakes exclusively for in-store pickup. The flow should feel as simple as walking into the shop: browse enticing product pages, choose size, flavor, and décor options, select a pickup date and time from my calendar, pay, and receive an automatic confirmation with pickup instructions. No shipping or local-delivery options should appear anywhere in checkout.

Key details I want built in:
• Clean, mobile-first theme that shows off product photos and flavor swatches.
• Product variants for size, flavor, fillings, and personalized messages.
• Date-and-time picker synced to the bakery’s opening hours and daily capacity.
• Shopify Payments (plus PayPal/Apple Pay) enabled.
• Automated e-mails and SMS reminders the day before pickup.
• Simple admin workflow so my staff can update inventory, blackout dates, and order limits without touching code.

Please attach a detailed project proposal outlining your approach, timeline, theme or app suggestions, and any similar Shopify food or bakery sites you’ve delivered. I’m ready to start as soon as I see a clear plan that covers design, setup, and a brief hand-off session once the site is live.
