Amendments to a Wordpress site

Hello, I have created the following website for university: [login to view URL] I require someone to do the following: - Implement infinite scroll - Add Pinterest integration - Optimise loading time - Fix the homepage image grid so that there is no overhang of div.img-wrapper (see attachment), which leaves a gap at the bottom of the page and obscures the fallback page navigation functionality. - Make sure the site renders correctly in all browsers (apart from evil IE6) - Fix the [login to view URL] plugin - Amend the navigation between the posts so that there are no page titles and the right arrow directs to an older post and the left to a newer post. (Currently it's the opposite.) - Create category pages. Currently the categories ('love' and 'unlove' in the sidebar) don't link anywhere. - Clean up the code, including making the markup and selectors semantic, so that making future modifications will be as hassle-free as possible Any further recommendations are welcome as part of your bid. I may have further amendments along the line (mostly up until the end of October). Please let me know if you will be available for this work. Thanks, Julia
