Data Entry - Need Variations Entered Into Wordpress

Hi - I am working in Wordpress using WooCommerce. I have successfully entered about 200 different kinds of coffee onto the website via the "Products" section. Each coffee is a product. They are categorized. What I need is someone to add specific variations to each product. (The way I would do it is by the "Product Add-On" Box on the right-hand side of each product listing.) This will most likely require you to go into each Product and add 3 variation text labels. They will always be the same and say the exact same thing. I will provide an example and give you exactly what to enter. It is not a lot of text for each Product. (18 words) I am looking for someone who has used WooCommerce and knows Wordpress really well. If something goes wrong during the process, I need someone who knows enough to fix the problem. Please only bid if you are CONFIDENT you can pay close attention to detail and you know WooCommerce and Wordpress very well. We are on a tight budget and would appreciate affordable bids. We will work with you - Thanks! *IMPORTANT NOTE* - If you are going to use a shortcut to enter these variations, you are 100% responsible if the site crashes or goes down. In other words, if you don't use the process I recommend above (Adding variations via the "Product Add-On" Box ), and something happens to the site, you are going to have to fix it. We've already had a database crash and we don't want any other problems. Thanks for understanding.
