💡 Feature: Setup package structure for each service

### Type of Feature

🎨 Style

### Current Behavior

We have scripts for each service + dockerfiles w/ dependencies defined.

### Suggested solution

Would like to have each service setup a project structure of:
  - sub-directory for the service
  - add pyproject.toml to define dependencies and packaging
  - add service-level testing
