DayZ Water Tank Script

I need a script for DayZ that enhances the operational features of a water tank.

The script should allow players to:
- Drink from the water tank
- Fill bottles at the water tank
- Wash hands using the water tank

Additionally, I need a vehicle inventory group system to manage vehicle inventories more efficiently.

I am looking for someone who can deliver this script ASAP. Ideal skills and experience include:
- Proficiency in DayZ scripting
- Experience with water mechanics in survival games
- Strong understanding of vehicle inventory systems in DayZ

Please provide examples of similar work done.
