I want to build an IOS app to book an appointment for different services. Haircut, Manicure, Pet grooming, etc. It has to have a login screen (sign with Facebook, Google+ or email), an intro screen with a carrousel view explaining how to navigate. Then it has to ask what service do you need and show you a list of the people in the proximity that can provide that service (of course they will be in a previous database). I need to be able to add people to this database trough the web browser and when the client choose one of those, It needs to show some of the information like "name", "telephone number", "experience", "description about themselfs", etc. When the client finally select the person, I should ask about the date when he wants to book an appointment and after it is confirmed an email/SMS will be sent to both parts.
