Referencing Web Service with Code

I did a search on the internet but came up with very limited results. I'm using asp/vb and need to create a n application that does the following steps:

1. User defines web service URLs to WSDL pages .. populated in combo drop down (already coded)
2. User selects web service - Clicks Connect
3. User is prompted for any input fields the web service requests.
4. Output (in XML) is displayed after input fields are populated.

I know how to reference web services in the development environment, and use them... but have no idea how to dynamically create them and show the input fields requested.

Any ideas/help???

You didn't search hard enough :)
