Create 3 high quality levels for a Unity3D Adventure Game

For the purpose of creating a presentable demo of my video-game idea I am asking a skilled level designer familiar with the Unity 3D platform to create three distinct levels, each unique in their approach: 1. Japanese rural countryside huge and open world. (terrain composer will auto-generate the expansiveness). 2. Dark hospital room, simple but impressive. 3. Impressive 1950's impressive. (the Smith's Home asset already has everything pre-built, you would only need to modify it). You'll also be provided with a huge assortment of assets that will aid in your progress including: Smiths home, Relief terrain pack, Substance database, Colorful image effects, Terrain composer, among others. You'll be in charge of adding the lighting to the scene, changing the textures, adding the world animations, effects and highly quality models in order to create a AAA quality level. I am not looking for professionals, instead someone willing to grow alongside me determined to create an excellent demo regardless of the established time period within my proposed budget - or close to it. I am a reputable freelancer with a perfect score and a 50% re-hire rate, so acceptance on this project is a long-term relationship with future ventures.
