Giving users access to post in front-end

Hey, forgive me if this is the wrong place and topic.

But here goes: I am building a website for a client and have found a great template that lets me do nearly all I need.

It’s a housing website and I need users to be able to register and post new listings. So far they can of course do this via the normal WordPress admin panel. This doesn’t satisfy my client though. I’ve found several plugins that will let users register, add new posts of the normal post type etc.

I basically need something that will let me users register in the frontend, preferably with functions like adding an avatar etc. AND have access to everything they would in the backend just without seeing the backend… If that makes sense.

The thing is in the theme I have there’s a custom post type called Properties with which you list new listings/properties and I need my users to use that function… From the frontend.

Sorry if that’s a little unclear, hope someone can help though.

Cheers in advance.
