Wordpress - Users with contact form on profile

I should build a site, where the users sign up and can create and customize a profile like a social media. But instead of adding friends to a friendlist (like fb ect.), all the sites should have a contact form from where the visitor could send them a request on email.

So basic requirments: User login and registration, Contact form on each user profile to contact the individual

How would you handle a job like that? Any smart plug-ins, that can help me on my way?
