Creating the payment work-flow for my app.

Hi, Please read the details carefully, before you add your bid. bids with no background will be not selected. 1) I have a IOS application ( not launched yet.) The application about football ( soccer), it sends notification once the goal comes to people who select their favorite teams based on the selection. if you select real madrid, you get notification once the goal comes, only for real marid, if you select two teams you will receive notifications for the two teams. 2) My developers, created a payment method and link it with Paypal. and now, we're changing the business model to be linked with Apple Account instead of paypal. 3) The finalized business model, will be based on 1) number of selected teams 2) period that user want to hold this team ( subscription ) i.e, if you select one team for 1 month, you'll paya x$, if you select 3 teams for 6 months will be 5x$. 4) users will have a free package once they download the application, i.e, 3 months for 2 teams and they pay nothing for this, and once the period ends, they have either to subscriber or select another package. otherwise, they'll not get notification for the teams. 4) The business model is as the attached. please read it carefully. it's very simple as the flow explains. 5) I have the backend for the app and the code for the app ready. 6) The winner bidder, will also have to create the same app for Andriod. not now, for the next phase after launching the IOS app.
