Wordpress WooCommerce Custom Plugin Development

General information for the website: Weekly Deals E-Commerce Shop
Num. of web pages/modules: 1 Plugin
Description of requirements/features: I need a new plugin from scratch because I was not able to find any plugin with exactly this features.

It should be compatible with the latest Woocommerce and Wordpress Version. Nothing too complex - to conclude I need the feature to add a estimated delivery date per product. This date can be different for every product so I need an editable text/string field to add the data.

The estimated delivery info should be displayed at the:
- product detail page
- checkout page
- woocommerce Order confirmation mail/order completed mail
- order overview woocommerce backend

Further requirements:
- Implemention at the live environment at the end
- Compatibility with all used plugins

And that's it! The Plugin should be ready in about 1 week. I am always available for questions during the whole task.
