Customize WordPress Custom Post Type Backend Listing Page

No Indian developers - your bid will be reported as spam. Looking for expert WordPress developer to do this for our existing custom WP theme site: On 'custom post type' backend listing page /wp-admin/[login to view URL] show these extra columns after “Title”: -------------- a) Author - original user who created the post b) Submitter – the last user who clicked on “submit for review” c) Publisher - the first user who clicked on “publish” d) Updated – the last user who clicked on “update” (usually is the publisher, but maybe different user) e) Category - the parent Category (our theme uses taxonomy for Categories) f) Department - the department of parent Category (our theme uses taxonomy for Departments) -------------- All above columns should have the default sorting feature to sort by descending or increasing order. Exact mirror of live site is installed on our test server, which you will have full FTP access to when project starts. IMPORTANT: a) Mention the word "CWC" as the first thing in your bid or it will be ignored. b) There will be lots more WordPress backend programming jobs for the right candidate, this project is just pre-qualifier job.
