Digital Menu Tablet for restaurants - repost

We already developed all admin/backend site. Products, menus, itens, prices, sessions, users, customers. Everything is ready, except Android app to run with customers. We need you to develop a software that uses our API to build android app. It will ask for all objects like itens, categories, images and send orders and payment info. All the enviroment uses intranet over secure wifi. The development will use remote database from our server but it must have configurations/parameters to change it later. Thats not a dificult project as we are already providing almost all inteligence from api.
