Looking for a theme

Hi Guys,
I’m new to WordPress so I’m not very knowledgeable so please excuse my question if it comes across as stupid.I saw this theme for drupal http://themeforest.net/item/bizreview-directory-listing-drupal-theme/8231637 that I really like but I wanted something very similar to use on WordPress but I can’t find any.There are thousands of themes to look through,so how do I find the right one for me?Exactly where do I look?
