Simple WordPress Theme / Plugin Modification

Need some basic modifications to a WordPress Plugin that creates a page layout. 1) I want to be able to use different templates based on category hierarchy. For example - Categories that have sub-categories will be displayed on one page template and categories with parents will be displayed on another template. 2) Also need to be able to add and format category description to page templates 3) Please include in response the phrase "happy new year" 4) Will require a new page template that is a modification of one of the current page templates Please see the attached file to better understand the pages. Two of the three page templates exist and will be provided for modification. The third is a close copy of the first and should be easy to create. I have also included the current page [login to view URL] files [login to view URL] is index in example file [login to view URL] will need to be modified to create "fender" page in example [login to view URL] is category page that will create "mustang" page in example This project is a simple project and I expect to have it completed quickly and will pay quickly.
