Modifying custom CMS (secondary language + jQuery)

We currently have a small custom CMS built within the CodeIgniter framework (PHP) that needs to have one of the views (and the only controller) modified to integrate the jQuery pluging Galleria (by devkick) as well as enable/integrate a 2nd language function for the end-user (english/spanish, currently site is in english) To give you a quick idea of what you're working with: the CMS controls 5 front end pages with dynamic content (the admin section does not need to be modified) We want to eliminate one of the pages using the Galleria plugin. The dynamic content should also change language when selected by the user. This should not take more than an hour for anybody who knows their way around codeigniter. Budget is 60$.
