Hi we need something custom

Hello, I have been searching for days now and i just cant find a plugin that gives the option to add a custom delivery date based on postcode.

For example State New York will be next week tuesday or in 2 weeks wednesday.
Its so incredibly simple and not a single WordPress plugin in this universe does this…

If you could add this feature to your plugin i would buy it immidiatly, I have wasted over 200$ on Delivery date from woo addons, Estimated delivery date plugins, and NONE OF THESE PLUGINS have this option…

IS this sooo weird to have as a feature? i dont understand…
