ASP.NET 2.0 Screen Scraper

Hello,
I wanted to try to develop a screen scraper I can use for a client but I am having some issues. Before I buy one I thought I should post the question here.  I need this solution as soon as possible so any help would be appreciated!  I need to go to various court websites and scrape the case data.  I then need to be able to write the data to a csv file.  I will need to continue to add data to the same file.  Can anyone help.  On the web, I was told this is an easy process but all I am getting is a copy of the screen and data.  I just need the data to be written to a csv file.  This solution needs to be in ASP.NET/C#.NET.

Thank you in advance!
