add field in woocommerce website

i have already install wordpress + woocomerce on new server. 1. In the woocomerce admin panel "Add New Product" i need to add new fields such as warranty time(2 years, one years, 3 month), manufacturer(provision, hikvision, dahua), there will be a select button with variables to select. remove sku fields from inventory tab to general tab 2. I want to have my part of the page that will be customized and there will be all the things I will insart into a product page together like: Product name, price, SKU, delivery time, warranty, manufacturer, all fields will be one after the other So it will be easier and faster to add products. all this detail i insert in backend need to show in fronent i sent pictures explanision for what i need and how its need to look.
