Do you know a CMS that can be adapted to a freelance exchange?

Question

CMS

3 types of user groups:
moderators, customers, performers
The last two have their own personal pages. Reviews.
Customers publish recordings to which performers can respond.
// For the purposes described above, any blog or forum engine could be used, but the following could hardly be implemented on them...
If the customer accepts the contractor's bid, their own project zone (correspondence) opens for them, while both people are outside the project cannot intersect.
So. Do you know a CMS that can be adapted to a freelance exchange?
Don't misunderstand... I would write in pure php myself (and very dirty), but I don't want to suffer any more nonsense...

Almost everything can be done on ready-made modules without the need to write code.

It's out of the box

The last two have their own personal pages. Reviews.

For reviews, you will need to create a new type of material (in the admin panel, not in code).
For each role, a page is themed (here you will have to make it anyway)

Customers publish recordings to which performers can respond.

Entries can be made a separate material, and reviews - either comments, as is the case in many exchanges, or also separate materials

If the customer accepts the contractor's bid, their own project zone (correspondence) is opened for them, and both people cannot intersect outside the project.

There is either a new type of material (project) with the possibility of correspondence in it, or a trigger like "if there are active works between users, allow correspondence"

Answer 5

Any blog or forum engine could be used for the purposes described above, but the following could hardly be implemented on them...

Almost all the necessary functions are natively in wordpress. For feedback, you need to replace the standard comment form on the projects page. Personal profiles are created for each wp user, but they are like his personal post feed, but you can add feedback features or even social media features. networks (there is even a plug-in such).
As for the maximum scale of the site, riotpixels.com is powered by wp.
