SOLUTION:
OK. I worked on it all last night and I made some progress. I used Fiddler to construct the POST message to see any discrepancies between what I had above and what the server expected.
I have got it sending the message and returning a HTTP 200 OK response. Again, this code is not production ready, its just something to test and see if I can get Zeep working. Thank you all who responded and if your looking for ZEEP code, I hope this can help you.
