App for new business

We are looking to develop an app for our new business. The app will be used by families to provide ideas for activities they can do together at home, in the garden or in the park for example. This should happen through the user selecting several options such as where they are, age of children and maybe number of children. The app will also need to be able to send the user places they can go to visit within a give distance from where they are. This would allow us to offer advertising spaces on the app to local businesses. The app should also be allow the user to register for membership to the new business. If possible, and I dont know if this is to much, please advise, I would like the user once they have registered as a member to have a a screen that shows there member number as a form of member ID? I hope this is enough info for you to get an idea of what we are looking for.
