electronic menu app

My project is about creating an android app to allow customers to order food and drinks from a tablet on their table in a bar or restaurant. It should allow the customer to login with just their name and email address. Then they should have the option of looking at the menu, ordering items which are then automatically sent to the kitchen app (which should be viewable on a tablet or tv screen) or sent to a tablet or screen at the bar if they are drinks. On a table the current 'orders' should show all orders placed for all individuals on the table and should update live. So the customers can see what eachother is ordering. Customers should be able to pay for their food when they like. There needs to be three options - pay entire bill (if one of the customers does this then it should show as paid on all tablets for that table. Option 2 is split bill evenly - therefore it divides the total bill and asks each person to pay their share. Option 3 - pay what i have ordered - on this option it knows what that user ordered and charges them that amount. The customer should be given the option of cash/card. if cash is chosen then a message is sent to the waiters tablet to ask them to take cash from table X. if card is chosen then it should give the customer the option to enter card details on the tablet or scan their card and enter the CVV number to make payment. if the customer entered an email then a reciept for the purchase is sent to them. if not they are prompted again, or can choose no receipt. On the back office the admin should be able to see current orders and payment statuses. The chef/kitchen should be able to add delte edit menu items and change quantities according to stock. The closest example to this system is just emenu in the UK. please study this website in full to look at their features as these are what I am looking at creating. I would like to work with someone who is committed to the project as it is going to grow and develop I have a budget for additional addons to this project. Any questions please ask.
