Quick Shopify Variant/Quantity Fix

My Shopify site needs a quick fix for the variant/quantity feature. It should be a 5-minute job for a professional. Please only apply if you can do this immediately and will do this for 5-10 dollars, this is a very simple job I just need it done quickly, I attached the picture of the issue - the quantity and variants are on the same line and ruining the look of the page, I need you to fix this across the site so it's standardized and fixed for all products
