Using Zeep with Python

I am trying to interact with this site for their SOAP service - https://eservices-test.cscfinancialonline.com/

I am unable to figure out how to call simple method based on their specs. I have tried to pass a dict, parameters, everything except the straight xml as zeep is supposed to do that for you. Just cant seem to figure it out - any ideas?

THis is what I have so far

import zeep
from zeep import Client

wsdl = 'https://eservices-test.cscfinancialonline.com/?wsdl'
client = zeep.Client(wsdl)

params = {'loginGuid': 'xxxxxxxxxxxxxxxxxxxxxxxxxxx', 'contactNo': '1', 'type': 'UCC', 'stateCD': 'NY',
          'companyName': 'Cullen'}

print(client.service.SubmitOnlineSearch(**params))

This is what mzeep spits out
