DEX land unity project (Webgl)

We need Unity engine where we have
- A huge empty map with HEX
+ The huge map size is 10.000 x 10.000 hex
+ Its split to many small land which is 100x100 hex
- A build engine to each land (like the game name THE SIM)
- An engine to submit Unity object to items list (which use to decor the land) - it could be outside of unity
- After the land be build and saved, it submit automaticaly to Huge Land environment

User flow:
- Connect to the engine and see the huge world
- Select the land
- Decor for it with free unity assets provided (decor example : https://www.youtube.com/watch?v=2OYr-uAzZb4&ab_channel=Mr.Olkan )
- Save the land
- The lands is viewable from huge world

You dont have to worry about the assets, we could use it from any free assets avaiable on unity store.
Budget range from 550 - 2.250$ depend on your team's deadline and quality of work proposal

We dont need any login system or blockchain system, we just need the unity engine (webgl)

Please provide previous Webgl job be done with Unity by you or your team which we could verified its your work.
