Hello Jtaylor, The easiest way I know to implement this is using Jayrock api/library. You can get more information by googling Jayrock.
One sacrifice you may have to make is to rewrite and rebuild your webservice using Jayrock's template which I believe is implemented as a custom http handler. They provide a very simple example that will get you up and running quickly and it is not really complicated to use and won't be much work if the web service code you will need to rewrite is not enormous. I hope this becomes of help to you. Please let us all know if it is. Cheers.

I exposed the webservice to the consumer, and they said it would work fine if it was not encapsulated in XML. So my only issue now is #2 from above.
