What cms engine to choose for working with clients?

Question

CMS

Greetings.
such a need, and now I can’t find the engine in any way, I
need to accept applications from clients, the application is just an electronic order to the manager, which includes several fields and an attachment , when the
manager receives the application, he must set the status of the application, and in response to the client make a vacation with an attachment
== ===
at least for this part of the client-manager interaction, which engine can I choose?!
=====
There is also a second need, you need to enter some kind of pseudo balance for customers
so that, for example, they enter a code from a coupon, the balance is replenished with credits,
how to organize all this?
Thank you for your attention!
