Teachers plugin

Hello there,

I’hv installed WordPress on my computer and using it through localhost as a self training. So, I’hv learnt basics of WordPress like how to work with themes, plugins, widgets, posts and pages etc.

Now, I want to create an app. Here is how the app is supposed to work:

Teachers will get themselves registered on the app. Visitors (may be registered/not-registered users) will be able to search teachers subject-wise or city/location-wise or by names etc.

Which theme, plugin(s) and widget(s) would serve the purpose?

Regards.
