Mobile app affiliate

I have a brand new app. I need to promote it and get subscribers. We are aiming 1000 subscribers. The subscribtion is 9.90$ monthly or 99.90$ annually. The app is about trading/investing technical analysis and is extremely useful for traders. We can pay you up to 25% for any subscription. Or fixed 25$ per subscription under certain conditions. Looking only for white hat promoters.

Thanks.
