Custom WordPress Plugin

I need a WordPress plugin created that will add one new page to the WP admin area for managing posts. The page will be a modified version of the WordPress post management pages (wp-admin/[login to view URL]). The difference is I need more information shown than the standard WP pages. Some of this information will come from custom fields in the posts. The good news for you is that I already have this page finished and working inside my wp-admin area. The page I have is made from editing the wp-admin pages. I need it converted to a plugin so that default wp-admin pages are left intact. The plugin also needs one "Settings" page that will be used for mapping custom fields to be shown on the custom manage post page. I will provide a screenshot of the current working custom page in my wp-admin, along with detailed explanation of each field in each column to anyone who asks. For the programmer who wins the job you will get access to my test server where the custom page is being used, so you can see it working and base the plugin on this page.
