SoapUI Pro 3.6.1

Hi,

We have to execute a stress test with below details:

•One test case with 2 requests: Get Users and Authenticate Users as test steps.
•We need to run it for '50 Get Users (first request) and 50 Authenticate Users (second request) after each 5 second’s interval for 1 hour'

Please suggest how to execute this type of scenario in soapUI Pro.
