Simple C# App

Hi everyone there. I'd like to have a C# app to run under Windows SO with next features: - No sophisticated GUI, a simple one. - The app has to create a text file in a selected path (configured in a Config file). - The app has to extract ALL the links available in this link: [login to view URL] - Each link extracted on that provided link, like these samples: [login to view URL] [login to view URL] and so on... has to be inserted in the text file mentioned in second point above (one link per line). Once the app extracts all links there, the app has to be finished their execution. - The execution has to be in background by default, no visible windows needed (configure the visibility or no in the Config file too). - The name of text file generated has to be "[login to view URL]". My max budget is $ 25, no more. This is a simple task, no more than 1 hour for an experienced developer who knows C#. Need this asap preferably. Thanks and good luck to everyone.
