Website Custom Development & Data Entry

Hey, My specific requirement is as below- I have a few WordPress(WP) sites on different themes, e.g- [login to view URL] & http://www.miamibizdirectory.com. As you can see, the coupons in this site [login to view URL] are just dummy & I would like an automatic coupon feed via API to populate my sites, this is for online coupons. I also need offline coupons feature where a merchant can register on my site & create a coupon from the the front-end, with each coupon having a code. I am looking for a way where a site visitor(consumer) needs to register on my site & download/email the offline coupons to himself/herself for physical shopping. Regarding [login to view URL], running on PremiumPress theme, I want that to be a directory site with a feature where merchants can list their company & also offer coupons/deals. Specifically I need the site to be auto-populated with listings across categories interfacing with Google business to pull in data via API. I need site visitors to be given loyalty points as & when they search & browse a business listing. These loyalty points to be re-deemed by them when they buy products/services from a particular business. Site visitors should also get notifications when businesses listed on the site offer deals as well as businesses will get alerts when visitors click on their listing. The site should be responsive, SEO friendly etc. I need a payment gateway integrated with the site that can accept Indian Rs, currently it has PayPal set up. I would also need an mobile app for the sites.
