Custom Wordpress Plugin for submitting data

I need a plugin for wordpress that will do the following: 1) Form field for the public to submit specific information to, text boxes, drop downs, etc. 2) Admin panel in WP that will be accessible to "Authors" and allow them to edit/approve/reject submitted forms from the public page. 3) Display results of the data, search by different criteria specified (some of the options selected) and text search of all fields in that specific db. Please send me links to previous Wordpress related work only. Thank you
