CRM Plugin

Hi
I am looking for a plugin that can help me with running my company.
I make wedding movies. I have some emplyees.
Now I want to be able to create accounts for my emplyees and my clients.
I want my clients to be able to view their services and pay.
I want my emplyees to see what users ordered (so they can get instructions for working) but NOT the price they pay (the price must remain between me and my clients).
I want myself to be able to view everything.

Can you recommend anything?
