C# application modify and develop job

Hello, I have application which is done by C#. It is tracking some selling website. App should be modified to work also for some other similar type website. Also app needs some more functions. Pls place comment so that we can start talking about details. I have work description list ready and will upload it for you. Also I will upload C# souces for you. BR, Harri PS. Later after this work, we may continue and make version which runs on server (because that maybe have better uptime than home PC).
