Buid a mobile application . Exp. Only.

Thanks for reaching me out and I’d like to inform you that we basically want to know first the average cost that will be involved in the development of an app with below description as for now: We’re running an activation in Electronics Retail Stores such as Virgin megastore, Sharaf DG, Jumbo which is a part of an awareness campaign, the app we require will be a part of engagement plan with customers going around these stores. We will put some hidden items such as posters, books and other items, these items will be hidden in these stores between shelves and sections, we want the application to read these items and display some information that will help people to complete the activation.
