Rimworld Custom Mod Development

I'm looking for an experienced modder to create a custom mod for Rimworld, based on an older, depreciated mod.

Requirements:
- Incorporate specific gameplay mechanics and custom items from the old mod.
- Use a provided PNG for in-game model; minimal animation required (rotation to aim at targets).

Ideal Skills and Experience:
- Proficiency in Rimworld modding.
- Experience with integrating custom graphics and animations.
- Strong understanding of gameplay mechanics and item creation in Rimworld.
- Ability to work with provided assets and ensure proper functionality within the game.

Please provide samples of similar work done.
