Request: plugin or theme for investors

Hello WP people

I am looking for a soultion vut not pretty sure how to search for it so i said let me write it here.

I need to make a website where clients will register, then will fill a concept form (for investment projects) then we the managment will see that form and comment on it, we = different users and we each will have differebt comments that r for internal use only. Then there is a relay to customer for his paper. So customer can follow up his paper through the site and see its status.
After that concept paper there are other files vut it will be same step.

So there is front end where customer upload his files and follow up which step he reached in the complete Application Submition.

And

There is internal use between us the team to see these files comments and maybe request other papers from the customer.

Hope some one can help

Thanks ??
