Add Local Pickup Button on Google Maps

I'm looking to integrate a "Order Pickup" button on my Google Maps page. This button should display a list of my products from my BigCommerce site.

Requirements:
- When the "Order Pickup" button is clicked, it should show a list of my products.
- The product list should be displayed within the current Google Maps page.
- Users should be able to view product details, complete an order, and pay using PayPal, Apple Pay, or credit card.

Ideal Skills:
- Experience with Google Maps integration and DoorDash and Square (I use Square Register on my physical store)
- Familiarity with BigCommerce
- Knowledge of payment gateway integration (PayPal, Apple Pay, etc.)
- Web development skills to ensure smooth functionality within Google Maps

Please provide examples of similar work done and ensure the solution is user-friendly and visually appealing.
