We are looking for a programmer and/or designer for an iphone (and possibly android) utility app; and only want to work with people who have experience in iphone/android development, so please send your portfolio.

App details:
-We are looking to create an app that will be similar to a clock timer, but rather than just showing numbers counting we will have images that will change depending on the amount of time selected (for instance, a sand timer that fills up in 15 minutes when 15 minutes selected, fills up in 2 hours if 2 hours selected, etc.)
-Multiple images will be used, the sand timer is just one example of the 6-12 we have in mind.
-Inclusion of sound effects may be considered, so please let us know if you are able to include that as well.

We mainly want to launch this on iphone, so programming in Objective C/Cocoa desired; with ability to program in Java for Android as well even better.
