Enhancing Environmental Textures in Blender 3D

My project entails advancing environmental textures, specifically focusing on realistic rain and water effects as well as weather conditions, within Blender 3D.

- Skillset:
- Strong familiarity with Blender 3D
- Expertise in texture enhancement
- Proficient in handling weather effects and water dynamics

The basic task is to improve the texture of environmental phenomena in my 2D image artwork: bringing rain to life and implementing more dynamic water and weather elements. The outcome should add a new layer of immersion to my project.

Please include any prior experiences, especially ones regarding environmental enhancements in 3D, in your proposal. Looking forward to seeing your wonderful work.

TASK TO BE DONE -
Can you help me with some Belnder Rain effects?
I want to do something like this from a 2d Image that I will provide -
1. https://www.youtube.com/watch?v=J4d-a7dVtiQ&t=4s
2. https://www.youtube.com/watch?v=2W-4Fetj1II&t=45s

To summarize something like this -
1. Rain effect
2. Rain droplets on floor
3. Rain stream falling from roof
4. Rain on glass wall / window

I will need help with bulk processing like 5 - 7 renders every week.
Can you provide the competitive pricing for the same.
