wordpress plugin that would only show local content

I am looking for a plugin or theme that would help me to only show local content.

I need it so the site would populate Blogs, Content, Advertising, Gallery, Etc. based on their location. It would need to use either login data (user Zip Code), zip code input or their IP address automatically. Their IP or after login user data would populate the site and give them the option to enter a ZIP CODE to change their location at any time.

Maybe this is simply a reactive plugin. I can’t find it anywhere though. I’ve been searching for weeks. Any help would be greatly appreciate in helping me find such a plugin or have one developed.

Thank you all in advance
