I don’t know of any company that does this on a commercial level - mostly because, as a manufacturer, if you buy a pre-made blend, you are helpless to fix it if it comes in as the wrong shade. This is also a problem because if the company making the blend stops making it, you are in very big trouble, especially if you don’t know how to make the blends yourself.
If you’re a cosmetic chemist, you will be much better off learning how to blend colors yourself.
If you’re a home crafter, just buy a set of mineral makeup shades wholesale and use those. You’ll be much better off doing that than spending 6 months or more learning how to colormatch.
