Servicenow On-Call scheduling setup

I am looking for a freelancer who can help me set up an on-call scheduling system using Servicenow. I already have an on-call schedule in place, so I just need someone to help me configure the system. I do not need integration with any existing tools, but I would like to integrate a specific tool that is not listed (which I will disclose upon hiring). Ideal skills and experience for this project include:

- Experience with Servicenow and on-call scheduling
- Familiarity with integrating third-party tools into Servicenow
- Ability to work independently and provide guidance if needed.
