Need my DEVELOPED iPhone app updated with a new function

IF YOU CANNOT SPEAK FLUENT ENGLISH OR DO NOT UNDERSTAND WHAT I NEED - DO NOT BID!!! I WILL REPORT YOU AND NOT STOP UNTIL I GET YOUR ACCOUNT REVOKED IF YOU WASTE MY TIME. I have a fully functioning, DEVELOPED iphone app (on itunes). The app provides restaurant details in any given city (menus, phone number, address, hours, etc.). I also have a cooresponding website and Android app. I have already hired a gentleman to do the website and the Android part of this. I need you to work with him (via email or gmail chat) to develop the iphone portion. He has already designed the script and the database. HE JUST NEEDS YOU TO ADD THE FUNCTION TO THE DEVELOPED IPHONE SCRIPT. I need to add an "order now" function to the iphone app. The restaurant will enter their menu via my website and the user will be able to place the order via their phone. They can pick which items they want and how many they need of each. They will then click "proceed" and will be taken to an order summary with sub-total and total with tax added. They will enter their name address email and phone number. If the restaurant has "delivery" turned "on" and the user selects the delivery option after clicking on "order online", at the sub-total screen, they will need to enter their payment information. They can then "edit order" or submit. A confirmation will be sent to the user. No payments will be processed through my site. All of the information entered will be sent to me via an email confirmation. If you need clarification, please message me.
