iPhone App Skin Design for Existing App

http://www.payoffdebtapp.com/apple/

Pay Off Debt app is a debt snowball app that's designed to motivate users as they get out of debt. They can organize their debt snowball, and see their progress. I created this app after becoming "debt free but the house". I wanted to help others do the same, and when I was getting out of debt I used to obsessively check my progress.

New and existing users of Pay Off Debt for the iPhone, and new users of Pay Off Debt Lite and Pay Off Debt for iPad (which will be coming out soon.)

SHORT VERSION: Redesign the Debts screen for iPhone and iPad, taking into account non-English languages.

iPhone Debts screen size:
320 x 480 and 640 x 960 (high resolution) - vertical only

iPad Debts screen size:
768 x 1004 (vertical)
1024 x 748 (horizontal)

Various existing screenshots are attached.

LONG VERSION: I'm looking for an original user interface design that can be built upon (possibly by me, later on) for all three versions of the app.

Current users have commented that they like the existing icon for the app because it focuses on a positive (PAID vs debt), but that the user interface itself is visually lacking, not very appealing, and that there should be a clearer way to differentiate between the debts.

I want something that has a "wow" factor but that also remains highly functional. (The current workflow is clear to users.)

I've attached the current app icon and screenshots from the existing iPhone app and upcoming iPad version. One of the design problems is that there must be room for Spanish & French translations of text. Feel free to ask questions.

I don't need finalized versions of the elements/buttons/fields, etc (although if you want to do that that's fine) -- just the design for the Debts screen itself in a format that I can finalize. Images used in the design must be your original work and not used elsewhere.

I'm looking for files that are in a format that can be scaled easily as size requirements change from time to time. (I have access to Photoshop CS5 and Inkscape, and could get access to Illustrator if necessary.) Custom image and artwork creation guidelines for iOS are available here: http://tinyurl.com/26prl5h
