From where could I obtain or how could I program a C# application in Visual Basic with the ability to load shells from a list, input target I.P./s, and the ability to take the chosen target offline. Is an online web host required, and is setting a custom timer for the target to be attacked within that duration plausible or simple? Please tell me everything I need to know.

"how could I program a C# application in Visual Basic"
Thanks for the laugh lol. I'm going to guess that you're programming in C# using Visual Studios, but I'm not giving any code, so Visual Basic would work too.

Load shells from a list.
- Read the shells from a txt file. Look up System.IO.File.
You could read the list from anywhere really. If you want the list to be on a site, use WebClient.

Everything else you mention is on the shell side. You'll need to send a GET/POST request to the URL with the correct parameters. Read up on the System.Net namespace.

"Is an online web host required"
No.

"setting a custom timer for the target to be attacked within that duration plausible or simple"
It would be stupid for a shell not to have a timer. You'll need to find the parameters that your shell(s) use(s) though.
