I need a coupon/ discounts iOS app

I need a pretty simple coupons/ discounts IOS app created that allows me to send push notifications when a new coupon/ discount is added on the app. The app needs to allow me to create a new ‘page’ for each coupon/ discount with a name, description and an image with a link for each one. I need a dummies guide on how to add content to the app and how to get it on the App Store (entirely new to apps in this way). I need to be able to add, remove and edit categories and subcategories that I can then add each coupon/ discount in to. It doesn’t need to be too flash, however I do need insights on the app for how many times a page has been accessed, for how long and just general insights including the gender and age of each person using the app (maybe a pop up when they go on to the app with some age/ gender/ location options?) I’m looking to start the project tomorrow and I’m not looking to spend tons on this so please don’t try and overprice your bid as I’ll just simply ignore it. I’m also not looking to be up sold once the contract is accepted, if you do this or even try to then I’ll simply terminate the project or contact support to get this done. Kind regards, Jamie
