Simple Wordpress Plug-in - Similar to an address book

Hello, This is an URGENT project, must be a very quick turn around - 1 or 2 days. It is going to be a Wordpress plug-in that is going to be added to an existing website. Think of it as a very basic phone directory / address book where you have a form in which you enter a person's name and if he exists in the database his first name, last name and address are displayed. If he does not exists an error message displays. The only difference is that the search will be made by the phone number, and not by a person's name. In other words, the user is asked to enter his special code/number into a search box, if it exists in the database it shows a bunch of information. The database could or should be a separate table in mysql which can be easily edited in either PhpMyAdmin or preferably, in the wordpress back-end in the plug-in's settings page. I've attached several screenshots/wireframes for both the Front End and the Back End. The db table will have these fields: index number | code number | first name | last name | address I would like to be able to edit this table and add/remove entries through the wordpress back-end... Finally, the plugin needs a shortcode so I can implant it in pages. For further questions please contact me.
