Even with wIRCd you have to configure files yourself, it requires prior knowledge to set up most servers. You could try a commercial offering but most cost thousands of $ for the privilege of point-click.
Using an mIRC script for an IRC server is, imho very stupid. An mIRC script is utterly slow, and it is also lacking. Any ASCII art becomes ruined by mIRC's inability to handle multiple spaces. And there are scores of other problems as well. Using an mIRC script for such an application is a horrible idea.
