>I am not sure how to create an ASP page though. What tool should I use.

Note pad :-) You can use InterDev if you got it, but ASP pages are just HTML pages running through IIS with some server side script code in them. Check out the Wikis topic if you want a crash course.

>Will I still be able to use the IASPI listner if it is an ASP page?

Yeah, rememeber, the server the ASP page is on can be a totally independent page that the Web Service itself is on. They're not related.
