I need a Windows-Programm made in C# that spider a famous search machine for different search phrases and protocol the sites which pay for promotion. When I mark the sites which are important for me, the program have to click on the link of that site and check it for updates.
The program have to make his checks in a random time between the (in menu) defined time frame (f.e. 30-60 min/sek).
To get a internet connection the program have to call a extern program and wait until there is a connection. After progress the extern program have to be closed. I will be able to select the extern program per menu.
