Restaurant Android App

Part 1 I require an android app created for my Restaurant where a database will be updated regularly with the customers name, address, mobile phone number and food delivery order, when the order is completed the order needs to be printed on 2 thermal printers, 1 in kitchen and 1 in the front of house for invoicing. We also require the items ordered to be printed on a separate labels printer for attaching on the [login to view URL] purpose of the database is that when the customers call again we can input the mobile/phone number to retrieve the address details previous order and date. Part 2 We would like to use the app to take orders by table numbers and the order to be printed in kitchen and stored on network until order is complete for invoicing for front of house and then allow printing for final invoice. We will be using more than 1 android tablet. Part 3 i would also like this app to be able to store the takings and give a breakdown of what customers are spending money on i.e food drink takeaways what dish is the most popular. which table paid cash card etc and the results emailed daily to the designated address. I require the data to be easy to input for the staff and operate and separate admin login, Maybe GUI or can look at recommendations by developer. I also want to use it for more than 1 restaurant that i operate, Data should be easy to ammend like a CMS.
