Replacement website on WIX. Needs to have a client/ member area with blog, images and other content

I need a new site to replace my current personal photography site.
I have broken my business up into various specialities so now I need to redo the content and structure of my site.

I need a general public set of pages for anyone who is looking casually

I need a protected client/member area for content that is not for public consumption. Blog, image galleries and other content.
