Build 3D room for Unity

Hi there! I need Unity designer to build/repear professional rooms for my project. I already have design and rooms made in Unity but need to look better, you have to create models/materials which can be used in Unity. Be aware that rooms should be perfect, almost the same as real photo. For start you will work on one room as a test and later there will be more if everything is okay. Budget is per room. Thank you!
