Recommendation for plugin / theme

Hi there,

I'm looking for a plugin / theme with which I'm able to curate a portfolio page as being seen in this dummy layout: https://www.evernote.com/shard/s108/sh/8774d934-8261-4498-b6d4-ecaddd3c0611/e07785fd569762a791ba1138eaa2197c

The upper left corner is the main menu.
The lower left corner is the submenu which displays the categories of the selected top category.

The lower right area displays all the images within one subcategory.

You shall be able to select a thumbnail image, which get displayed on the upper right area. You shall be able to page through all the available thumbnails.

Thanks in advance and best,
Julian
