I need a simple Exit Redirect Wordpress Plugin designed which will have the following...

1. Plugin which can be enabled & disabled in Wordpress
2. When enabled, the plugin will have a settings page which will have a URL input box which the owner of the blog can input and save a Exit Redirect address URL.

This needs to be designed so when a visitor visits the Wordpress Blog and leaves they will be redirected to the URL input box address.

Unlike other exit scripts, this script will NOT have a popup message asking the visitor if they want to leave or any built in method trying to keep the visitor on the site. When the visitor exits the site they will automatically be redirected to the URL input box address.

I plan on marketing this plugin so it needs to be made so anyone can easily install it on their WP Blog.

I'm on a budget so lowest bids will be considered first. Here's a video with more info - http://youtu.be/WPJZg75tuaQ

I would also like to have a simple Java Script code version of the Plugin with the same capibility to redirect a visitor to a URL which will work on any HTML or PHP site.

When the visitor clicks the back arrow to leave the site, they will be redirected to the URL the site owner added to the script.
