Project Description:
I am looking to build a simple iPhone application.
App is similar to existing application.
App is meant to do the following:
User opens the app, and being asked to add a bank account (no worries - no real link to actual account needed).
User adds a bank account (user names it as he/she likes).
User adds funds to this account.
User than presented with this Balance on top bar.
User than adds transactions made - either income or expenses.
So for example, user can write "+ $100". App will automatically add this amount to the initial balance.
User can also write "-$100", and app will automatically deduce from original balance.
Very simple.
User can have multiple accounts.
All done manually.
Very simple app to write.
App must be super-fast, even on iPhone 2G (the first and slowest iPhone).
App needs to be able to require passwords (numeric, nothing crazy) in order to view balances and accounts).
App needs to have Currency chooser (simple, if user chooses currency X, than app will use this currency).

Graphical interface: must be as I demand it to be.
Will be similar to MAIL APP of the iPhone - clean, simple, easy to click on.
Might include other graphic elements to make this app very visually appealing! This is VERY important!

App writer must work with me throughout the process till honed to my desire. App writer must be able to complement the app with beautiful design!
The most important thing for this app - beautiful design!

App must be able to have IN-APP PURCHASE.
I don't know what this requires, and app builder/writer will have to work with me and explain to me what is needed.
Upgrading to the PURCHASED version may have SYNC option with Gmail/Google Drive. I am not sure if this is possible, but it sounds easy enough to implement, as data needs to be sent to user's GOOGLE account (Gmail account can create a new tag in Gmail and store the data to prevent data lose in case of lost iPhone or deleted app).

Looking to hear from interested developers if task can be completed in a desired manner.
I again stress out: app must be beautifully designed!
App also needs to be native (not-HTML5) for faster performance and responsiveness. There should be no lag whatsoever!
