Don't worry, I have it.

I have set up 2 clients (1 mIRC with NNS loaded, and 1 raw mIRC) and put a last said script on the raw mIRC (found here: Modified 1 thing to make it more specific, and loaded this script onto my client:
on *:TEXT:!help*:#(targetchannel):{
  /msg #(mychannel) Help called. 
  /msg #(mychannel) !ls $nick

And it works now!

Thanks to those who took their time to help.
