Need ClickFunnels Help - How to Implement One-Time Coupon Codes

Hello, I'd like to implement one-time use coupon codes into clickfunnels. Customer lands on our landing page, clicks a button to claim the code, enters their name and email, and the code appears on the next page as well as in their email. If you know of a way to do this easily, bid on this project. All I need to know is how to set it up. If I am able to set it up correctly based on your help, you will win the project.
