Small changes to my existing iOS drinking game

Hey, My app is currently up and running, and can be find here: [login to view URL] I have two options for users to access the locked modes. One is to use Rewarded Video ads, the second is to purchase the IAP for 5.49$. Now I want to only offer either to unlock only ONE mode for 1.99$ or both together for 2.99$. So the popup-screen which offers the rewarded video option or the IAP purchase option needs to get editet. It is an really small task, but I am seeking for a long term partner to do also do other work on our app.
