Google Form Conference Approval Automation

I need a Google Form to request conferences for my employees, with an automated approval hierarchy. The form should include:

- Employee name and department
- Conference title and date
- Purpose of attending the conference

The automation should route the request through all necessary approvers in the submission chain.

Ideal Skills and Experience:
- Google Forms expertise
- Experience with approval workflows
- Familiarity with automation tools (like Google Apps Script or Zapier)
