I have gone through your description that you need a place lighting in kitchen and living room. How far apart and distance from walls ect.
I have been a 3D artist working on virtual reality projects for 8 years. My skills include modelling, texturing, environment art, lighting. I am able to create assets from scratch or modify and optimize existing ones from any marketplace.
