Custom Island Terrain Mod for Arma 3

I am looking for someone to build a custom Arma 3 terrain with an Island theme similar to Hawaii. The terrain doesn't need to be populated with static objects (buildings, roads, trees, etc) but will need the basics (heightmaps, grass, sand, etc). The person who performs this project must have a working knowledge in Arma 3 Tools and be able to see the project to completion.
