Edit Landing Page

Not sure how much this would cost, I need help editing the landing page at

http://themeforest.net/item/lista-landing-page/full_screen_preview/233986

I want to delete everything below the video minus the big button and the facebook comments. Also I need to edit text and some of the text is on image.

Pretty basic simple job shouldn't take too long, please let me know asap if you can do this.
