570873 iPad App Programmer Needed 2

Apple iPad utility application. Think of it as a big app with 4 more secondary apps inside and 3 utilities. The design has already been made: a skeleton made from basic iPad2 interface elements and the graphics that will used as a mask for it. The 4 secondary apps are grouped in two categories: first two are similar in design but calculate different things (object expenses / miles and gas expenses), the last two calculate sharing a bill or resolving the summary of a long trip between the participants (who owes who and how much) and a running tap for a single person (lending money to someone constantly). The utilities are Calculator, Tip Calculator and Converter (this will include Currency too). The budget for the app is: 1500 US Dollars.
