Oh man! You are sitting on a gold mine. I am not sure if YouTube hasn't approved your monetization, or you haven't applied? But let's say you are not allowed to monetize your channel for what ever reason. Make an ecommerce store! Start selling physical products. If you are not located in the U.S. then start some sort of dropshipping ecommerce store. What about sponsorships? But where you are going to make the most money is selling physical products. Or by selling affiliate products. Find a store that sells physical products like Amazon, and do reviews on certain products. Remember, to make money, you have to sale something. Whether you are selling it as your own, or as someone else's product.
