Need an adroid application for restaurant - Digital Menu

Digital Menu -Display categories(should be flexible to add/delete number of categories, like veg, non veg, further it can be lunch, breakfast etc....) -User should be able to select/add the dish. User should be able to select same dish multiple times. -Selected dish should be accessible/viewable all the time. -User should be able to view description of dish This part is can be exactly developed as in Inn Menu:[login to view URL] Backend: 1. Menu can be synced with server 2. There will be different menu for different devices. So sync needs to be done for particular devices for particular menu only. For example, if restaruant1 (MENU1) has 5 devices and restaurant2(MENU2) has 3 devices. Then whenever I update MENU1 on server, only devices that belong to restaurant1 (number=5) should be updated and not of restaurant2. Server should be notified about successful sync. Also, I'll need freedom(even in code, not necessarily GUI at this point of time) to change fonts, colors, customize logo etc..) . Once I'll have code, I can make APK myself for every restaurant.
