App design for Golf Course

I require an application developer to develop an app that can be used to track scores for a golf resort with 18 holes, inclusive of hole by hole information as they reach the hole, using gps pinning. We would also like to include an alert for the cart shed that uses gps pinning to determine which hole the golfer is at so we can send the refreshments cart to them. We would like to offer guests the chance to 'check in' to facebook once they open the app and once the round of golf has been completed we would like the results to be sent to the clubhouse so they can be printed for the golfer. Weather updates, current golfing conditions are also to be included. The golfers statistics (scoring average, putts per hole and driving accuracy, handicap entries) are to be included as well as the ability to add 'friends' The app swing by swing has a similar idea to what we are looking for, the home page asked the guest to either sign in with google+, facebook or via email. with the slogan that 'we will never post for you'. The Vintage Golf club has a similar app as well.
