I need marketing for my paid app/game

I have to pay you for the number of sales you will bring. So I've got a much better offer: i will pay you 0.5$ dollars for 1 sale ! check this out: 1- 1 sale = 0.5$ 2- 50 sale = 25$ 3- 100 sale = 50$ 4- 1000 sale = 500$ and it will be going like that! if you finish your work and bring 1 sale ! i will pay you 0.5$ . not 100$ !! if you finish your work and bring 1000 sale ! i will pay you 500$ dollars . not just 100$ !! And you should know that I don't have a Facebook, Twitter or Instagram page. So your focus will be on promoting the game only. And I don't have YouTube channel. My app price : 2.4$ dollars Keep in mind that I will pay you from the sales you will get, that means I will not be able to pay you if you got 0 sales! Now I was frank and clear with you. I hope you appreciate it.
