we are a web design company with numerous small business clients looking for iphone app development. this project is a pilot/test for us to find new development partners. we have steady ongoing work, and require experienced developers for long term partnerships. this project is for a small takeaway restaurant. approx 50 items on their menu. the app should allow customers to place an order from the menu. we will also require the app to send an email notification of the order to a designated email address. (or you can propose your own notification solution, if you have an alternative)
