Hey there lonely wanderer. A module for Magento 2 that may spark your interest. And its open-source. It will enable you to price your products for specific customer(s). This implementation is a working template, but certainly not final.
This module adds a new price type: customer_price and injects it into the quote calculation which is required by Magento 2.
The customer prices come from a table itonomy_customerprice which is not accessible (yet) through the admin panel. If you put a customer_id, product_id, website_id, and price in it, it will magically update the prices for that customer. Wow
Just the regular stuff
composer require itonomy/module-customerspecificpricing
