Restaurant App required

I need someone to design, develop and launch (to App Store and Google) a restaurant ordering app very similar to https://apps.apple.com/gb/app/shama-bingley/id1504083783
The app doesnt need to take payments yet (may be required in the future) so cash on delivery is the only option.
Customers need the option to "create account", "login to account" or "order as a guest"
When the order is sent to the restaurant it must be in the correct order (starters, mains, sides etc) irrespective of the order the customer adds the items to the cart (the app must sort these to the correct order).
Thanks
