Touch screen ordering system

Hello, We are looking for a team or a person that can develop a touch screen ordering system for restaurants. System should be easily modified later on to make different designs and customisations according to the customer needs. System should consist of 3 parts: touch screen menu at the table (with games and table to table chat), kitchen side(where chef can see the orderes) and online backend, where customers can change menus, pictures, prices, special offers etc. Also we need a digital signage soft, that has an online backed (for managing time tables, videos, pictures and multiple displays at one site and multiple displays on different locations) It would be great to find someone that is willing to work us with this product for a longer period: make customisations according to customers needs, make different designs etc. So far we have thought to build the system on nuiteq snowflake. If anyone has better ideas, please let me know.
