For each download, I'm charging 1$ as fee. This is a chrome extension by the way. I pay 5% commission to Chrome. 10% to designer.
I will pay you 40% for each lead you generate / for each download that happen. The requirement is absolute, People will seriously love it. I can give you the link to go through the existing reviews.
Just make it to reach people, they will automatically download it. You will be paid 40% (More than the creator or developer earns).
