Data entry/Upload all the fashion shirts: data entry (I will deliver a website where you get the data from) 2. Upload high quality product images (these pictures will be downloaded from the same website) 3. You have to add SEO details on the product like Page Title, meta tags, product Keywords etc into the data entry screen. You need to get this information from the same website.
