App with GPS Navigation and Chat function

Main function of the App will be to connect min. 2 max. 10 people with each other or guide them to a meeting point over the integrated Map and GPS from the device. The App should also have a chat function integrated where the users can send messages, images and videos under each other. The User Identification should work over the Users Telephone Number. Means each User needs to add his Telephone Number first and receive then a code back to verify his identity The App should send push Messages to other users when they receive a chat message or another user wants to share his position with him. The following Menu buttons are available: Map – Connecting option with other users over Map/GPS Chat – Chat with other users, send images and videos Settings – Make settings for chat, Map etc. Profile – User can add a profile Photo and can change his name Contacts – Shows all contacts which are in the users telephone book. I’ve already created a detailed Specification for this Application and made already the design for the whole Application in Photoshop. Needs just to be implemented into Xcode. Please only send a Message when you're 100% sure that you're able to develop such an App and you've experience with GPS and Chat within an Application. Budget approx. 2000 USD
