Market place app

Hi The App aims to connect users and shops of a certain area displaying the best deals available in store. On one hand the user-buyer will open the app signing up via FB IG Gmail or directly with a username, password and email(photo). Then they will have the chance to search for the products they want choosing from the different categories or stores available(photo). Alternatively with geo-localisation they can find the closest shops in their area (photo). Users will have the chance to buy directly online or to "book the purchase" that has to be completed within an established amount of time before the deal expires (photo). Ultimately a rewarding system will let users to accumulate points for every pound spent via the app (photo). On the other hand Shops' owners will have to manage their online stores updating inventory, prices and discounts in relation to the physical availability of the products they want to sell on the App. The stores will have access to useful data such as impressions, conversion rate, customers gender, age, hours and location(photo). This is just a short brief to asses the resource/skills required on back/front end & design level. I would like to discuss this further before starting the project. Screenshots taken from various App to picture the idea.
