Skilled C#, Win32 Programmer Required

We are seeking a skilled C#, Win32 programmer with at least 5 years experience building Windows GUI applications to help us complete an application which is already about 85% finished. We are looking for a developer that can quickly understand how our current application works, and can get up to speed quickly to help us finish the project. The application is a (web-service based) client application (no server code required) which allows users to review text files stored on a database, create simple audio files and send them to a web sever; and then arrange JPEG photos into a slide show. The Consultant who built the application for us finished most of the work, but left for a new project before he completed the remaining features and testing. Building the application took about a month. The business code is relatively simple and is almost complete. Most of the user interface code has also been completed. The current code is good quality work. Our developer has reviewed the code and made some corrections, but he does not have much experience developing user interfaces, so we are looking for someone who does. What needs to be done, 1) add some new features that were not finished yet, 2) Make some usability enhancements to the user interface, 2) fix the small bugs that cause errors, 3) clean up the structure of the application, 4) testing various scenarios to be sure the product is stable and reliable, 5) look for ways to improve the performance, 6) create an installation package This project requires understanding of object oriented coding, data structures, Win32 GUI, Windows installation packages, and requires MS Visual Studio 2005. We estimate that the remaining work could be done in around 40 - 45 hours by a skilled developer.
