Hello, i'm an architect proficient and certified in several 3D softwares (3D Studio Max, Rhino3D, Maya, Cinema4D,...) and i can help you modelling your sunglasses.
Please check my portfolio or interview me so i can show you some more samples of my work. I can reproduce any object and any texture in 3D, still or animation using Vray render engine.
I can start right now and work whenever needed.
Thank you, my best regards,
Humberto Ferreira
