"Find" custom menu item

System

Does anyone have a good 5.5.2 custom menu item for find that they would be willing to share? I would like to give the users four textboxes, two for filename (one regex, one exact) and two for text (one for regex, one exact). It should not allow exact if regex is entered and vice-versa. It would look in all files under their current directory for matches. Another thing that would only take a few hours to develop that should ship with the product (as an option if performance is a concern)...
