How can I create an on-demand service request?

Here is the Vtiger process flow for on-demand service requests:

1. A case is created to register the request with Service type as Service Request. 
2. A work order is initiated from the case and dispatched to fulfill the service request and linked to service. 
3. The location is set to Onsite or Remote based on the location of the service.
4. The service (labor) is billed according to service cost defined in the price book.
5. Any additional service performed during the service request is billed at the service cost as mentioned in the Price Book.
