Create a wordpress/woocommerce plugin for me

I need a custom plugin created for an ecommerce website. The plugin is for purchase orders for my suppliers. This is a backend plugin only. I will have "incoming stock" from suppliers, that is not to be added to stock untill i confirm the purchase order has arrived. What this plugin requires: 1) Allow me to add as many suppliers as i need 2) Allow me to add orders of woocommerce products and quantities for a specific supplier 3) When those orders actually arrive, i want to be able to click "confirm" and all the stock from that order should be added to the frontend stock of the website. I have attached a PDF of the layout of how this plugin should work. If you have any questions or are confused please ask me. Note: If you have bad english, dont bother applying for this task, I prefer to work with people who can properly understand my needs.
