Javascript / HTML / Wordpress programmer

Hello, I need a programmer who can rebuild this page for me: Example: [login to view URL] the code on the page is very heavy, and relying on a lot of libraries. I need the code to be as clean as possible, and 2) make it possible to add a second and a third section, which should work independable from the first one. The code on the example page does not work like that. So, basically I need the following: One section with 5 photo's. On click, photo slides to the most left position and a text is shown. Other photo's disappear. On click out (x), the photo slides back to it's original position. The second section: One section with 12 photo's. On click, photo slides to the most left position and a text is shown. Other photo's disappear. On click out (x), the photo slides back to it's original position. When clicking, Section 1 or 3 is not changing. The third section: One section with 6 photo's. On click, photo slides to the most left position and a text is shown. Other photo's disappear. On click out (x), the photo slides back to it's original position. When clicking, Section 1 or 3 is not changing. Please look at the example, but please program the code as clean as possible from scratch. Do not use copyrighted code from the example website. The code (html + JS) should work in Wordpress. Preferable through a plugin, but using html pasted in a WP page is also fine.
