In Amazon, to become a verified seller you have to register yourself as a seller and you have to receive a TIN number from the tax department . I have no idea whether this works here or anyone is free to buy and sell on his own .
I do not think its even worth it, I would just sell it here on the forum and on some other forums, its depending on what you want to sell of course.
You can also use Openbazaar or Bitify as example.
One feature you might going to like about openbazaar and bitify is buying and selling anonymously
