Developer needed to create Shopify customization and integration with shipping app.

I am setting up a Shopify online store for my food business (Fish Market). We offer local delivery, store pickup, and shipping. I am using existing Store Pickup & Delivery App to allow customers to select a date for their delivery, following certain rules that I have set up. The store has both English and French languages.



I would like to take pre-orders for products that will be in stock at a future date, the "Product Availability Date". There are several apps that allow you to take pre-orders for out-of-stock or upcoming products, but the delivery date is not set in accordance with the product's availability date.



The customization I am looking for is the following:



1) Allow merchants to set a "Product Availability Date" per product or for an entire collection. This data is stored as a metafield or tag on the product/collection and is easy for the merchant to bulk-edit.



2) Display the availability date on the product page and in the quick view page, right above the add to cart button.
