Develop an UI and some extensions for an OS X application

Hi everyone, we need a cocoa developer to develop an UI for an OS X application. The application already has an UI but we need to change it to adapt to our company guidelines, and we also need some simple, extended functionality. The application will search and download series from the internet. The downloader engine and a sample UI is already developed, but we need to add a queue for episodes that are downloading, and including an ffmpeg optional conversion step to change the episode format, etc. Further details to be provided in a per-candidate basis. The development work is very simple and we expect it to be done in about 1 week. Regards, Alberto
