Godot 4 Developer for Weather Prototype

I need a Godot 4 developer to build a small technical prototype for an ambient 3D weather environment.

This is NOT a full game yet. I want to test the weather/simulation systems first before spending money on the final 3D environment.

Prototype requirements
Godot 4 / GDScript
3D scene using simple placeholder assets
Controllable rain intensity
Controllable wind intensity and direction
Lightning flashes
Thunder triggered by lightning with a believable delay based on distance
Layered weather/environment audio
Basic environmental reactions to wind/rain
Simple local control panel to change weather variables in real time
Standalone Windows build

The code should be structured cleanly so additional weather systems can be added later, such as snow, waves, more environmental reactions, and eventually external controls.

Important

Visual quality is NOT the priority for this first prototype. I care more about the underlying systems working well and feeling believable.

I do NOT need Twitch integration yet.

I need the complete editable Godot project/source files at the end of the milestone, along with any documentation needed to understand the systems.

Please show me examples of:

Godot 4 projects
3D work
Weather, VFX, particles, shaders, simulations, environmental systems, or similar technical work

Please include your hourly rate or fixed-price estimate and your estimated timeline.

I am looking for someone I can potentially continue working with on future systems if the prototype goes well.
