WordPress WooCommerce Need

We need the help of a good programmer to make the following change to our WordPress site that uses WooCommerce. 1. We currently have a custom cronjob running that makes it so that when a product is no longer on "sale", the product is automatically marked private. We would like to change it so that, instead of marking it private, it removes a category and also removes related products from the product. That is, if a product is in category "Sale" while on sale, as soon as the sale expires, we'd like the product to no longer be in category "Sale". All the hard work is already done as this is just a simple change to the file that we created that currently makes it so that this product is marked as private when the sale ends. I estimate that the entire project will take less than 30 minutes (and probably less than 15 minutes, if you are familiar with WordPress, WooCommerce and PHP). 100% payment upon completion of project. If you cannot accept this term, please do not bid.
