Youtube Audio + Video Downloader - repost

I am looking for someone to create a .net application written in vb, or c#. I will need all source code to application. I would prefer you use a library like youtubefisher if needed. The application will allow the user to upload a .txt or .csv and add it to a grid within the GUI. The file imported will contain 2 columns 'Download type","Youtube Video URL" Example Below: video, http://youtube.com/videoid=23432432423423 audio, http://youtube.com/videoid=23432432423423234 audio, http://youtube.com/videoid=234324324234232 video, http://youtube.com/videoid=23432424423 Depending on what the user listed in the .txt file to download, it will download either the video, or the audio. The user will need to have to set some defaults like "audio save location", and "video save location" The video download type should always be highest quality. See attached for images.
