Create a Wordpress plugin to increase Woocommerce product price based on inventory remaining.

Create a Wordpress plugin to increase Woocommerce product price based on inventory remaining. Objective: I'm selling art on a wordpress "replete" theme using Woocommerce. I want the price to go up as the art sells. I would like a progress bar depicting this. Important: I am using variable products. Specs: - Website is [login to view URL] - Example of current product page in attachment 1 - Example of desired product page in attachment 2 - Stock remaining progress bar should go down as inventory sells out. - I'm using variable products. Please don't forget to take this into account! - I need a place on the edit product page to define starting price and ending price. I'm assuming this should be managed under variations. - Price should increase every 5 pieces (not 1). So to determine the next price, you need to look at the inventory count, remaining inventory, and the starting and ending price - Important, I don't want to display the actual number of remaining products in inventory on the product page, only use the progress bar. - If someone purchase more than 5 products, the price will not change. Just change the price after the purchase. - Please don't mess up responsive - Please write clean functions and use your own namespace
