Which solution is suitable for creating a "store within a store"?

Question

CMS

If you explain in general terms, that is, TK. One of the features of the store is when the seller registers himself and starts selling his own goods of various categories and directions. Each of the goods can have its own set of characteristics (such a mini-aliexpress).
Firstly, how much can the most budgetary version of such a solution cost?
Secondly, is it possible to run something like this (at least with minimal functionality) on OpenCart / Woocommerce, etc., or is an individual self-written solution needed? What will be released faster? Can you suggest other options.

why are there no sensible plug-ins?
because the niche is closed EVERYWHERE.
your project is doomed at the start ....
