Character Model Rigging for Source Engine

I have a character model that requires basic rigging for the Source Engine. The rigging should be sufficient for standard animation and movement, but does not need to accommodate for complex maneuvers or facial expressions.

Ideal Skills:
- Proficiency in Source Engine and its model rigging standards
- Experience in basic character model rigging
- Ability to work with existing models and make necessary adjustments

Please note: The model is already created and needs no modifications prior to rigging. The focus of this project is solely on the rigging process.
