Custom E-Commerce Plugin for Weekly Deals Shop

I'm looking for a custom plugin to be developed from the ground up, as I couldn’t find any existing plugin that offers the exact functionality I need.

The plugin must be fully compatible with the latest versions of WordPress and WooCommerce. The main functionality is fairly simple: I need to be able to set an estimated delivery date for each individual product. This should be a custom, editable text field so I can enter different dates for each product as needed.

The estimated delivery date should be displayed in the following places:

Product detail page
Checkout page
WooCommerce order confirmation and order completed emails
WooCommerce order overview in the admin backend

Additional Requirements: Final implementation should be done directly on the live site and must be compatible with all existing plugins currently in use

The plugin should be completed within approximately one week. I'm available for questions or clarifications throughout the development process.
