Code Wordpress Plugin to work with Twitter's oAuth

We need to customize the wordpress plugin, Social Hashtags ([login to view URL]) to allow us to get posts from Twitter with a certain hashtag. We have installed and configured the plugin. It currently pulls posts from instagram into a "social posts" section of the wordpress dashboard. Currently Social Hashtags is installed on a test site [login to view URL] On the dashboard of the test site we are able to access and edit the title, text, image and date of the social post and display all of them on the front end of the wordpress on a single page here: [login to view URL] We just need to also be able to get posts with a certain hashtag from Twitter. There is a possibility of more work for you once you are able to do this one task.
