Wordpress Business One Page theme by Rara 2

Hi. I need someone who’s VERY good with Wordpress, JQuery, PHP, css, js and anything related. I am now building a one-page/scrolling website with the Business One Page theme by Rara. Background information: The theme provides a slider feature that comes with a title and button. Because the slider must connect to a post, the slider’s title resembles the post’s title and the visitor is taken to the post after they click the button. I already modified this part: by placing a jQuery script in the website’s footer section, I managed to redirect visitor to the testimonial section after they click the slider’s button. Now I need someone to work on some more modification as follows: 1. In slider right under the title, display paragraph from the post’s body text. 2. Navigation menu is gone from width 768px to 991px. 3. Remove white space on the right side. IMPORTANT NOTE: I cannot give you my Wordpress or FTP login details. So I need you to show me instructions via texts or Teamviewer. Thanks.
