Is there a service for selling personal files that is similar to Filesprout or Sellbox?

Question

Electronic commerce

Please tell me a service for selling personal files.
Here's what I mean:
1. The client orders the work
2. I do it, I eventually have an archive with the order
3. I upload this archive to my server (or my Dropbox, Google Drive, etc.)
4. I go to the service website, enter a link to the archive there, set the price, etc.
5. I receive a link from the service, which I send to the client by e-mail
. 6. The client follows the link, makes a payment there, and only after that receives an archive with the order.
Important conditions:
1. Nowhere you can see all my products. Each product should have its own showcase, not related to other products in any way.
2. The service should not have any showcases where my goods would automatically go. Each product is intended only for the person who ordered it.
There used to be a suitable service, Sellbox.com, which, unfortunately, no longer works.
So far, I have only found Filesprout.com , which I don’t like because it has a Marketplace where user products go. But the commission is only 5%.
All other services offer only the creation of their showcase with the expectation that all products should be visible to as many people as possible.
Maybe there are not whole services, but separate scripts for the site for these purposes.
