Wordpress Voucher Code to Page/post Redirector

I'm looking for a plugin for Wordpress that would allow me to issue a unique code to a user which when used loads a specific page. I would need an Admin panel that allows me ADD and REMOVE Codes and the select a page from from a pull down list of all pages/posts available on my site. There needs to be a shortcode that can be placed on customer landing page for the user to enter their code and click a button to load the associated page example: Code = XYZ1234 Entered into input box and when user click the Enter Button the page associated with the code is loaded
