Collaboration service for freelancers?

Question

Work organization

I ask the community for help. Suddenly who met such a system.
We need a very simple system.
there are 3 freelance rewriters
I add text for rewriting rewriters
are notified by mail
who has time, comes in and chooses himself as a performer, the rest see this and do not take this text for themselves.
Everything, nothing more is needed.
You can use an online service or a WordPress plugin.
I re-read all the posts here on this topic - there are a lot of services with great functionality, but there is no simple one ((They are mainly focused on teamwork

Answer 1

Well, the point is that there is no way for a bang to unequivocally choose himself as a performer. I thought to make a sheet through Google, again it can overwrite. and then look for who was the first to edit
Found the answer to my question on the toaster, teamer.ru

Answer 2

You can use a regular CRM system, such as Feng Office.
