Remove author and next article from footer of project/portfolio pages

Hi all, Here's the reference link: http://alanawaters.com/index.php/portfolio/campaign-photography/ I need to remove the blank footer column, then the middle with the "Published by Alana...", and the third with "next post". I've looked and looked and I don't see anything for pulling that out. Can anyone suggest a fix? Thank you so much! Alana
