I offer bases (digital files) on Gumroad, such as reference sheets or badge bases. You can buy my Photoshop files on that website. After downloading, you can adjust and color the files as you wish and use them for example as reference pictures, badges, avatars, etc. More will be added in the future.
Examples and more details you can find on the product pages on Gumroad:
