Simple Button, Users Can create a post

Hello

I’m creating a WP page and I’d like users, who are logged in, to have a simple “post new” button and a simple screen to create a post. I hide their access to the admin page now to keep things simple. I don’t want them to go to the existing “add new post ” option that is standard with WP. It’s too many options. Simplify, Simplify.

Is there something like this already ? Is there a plug in to do this ?

Your help would be appreciated !!
