I will provide to you a 3D STL file, created by NURB industrial design way. This CAD/CAM option have much more tesselations and quality surface to be a better real model(3Dprint). Because the surfaces are done by directriz and generatriz degree three, like "class A" of manufacturing prototiping.
I will give to you a real photo render using Maxwell unbiased rendering, with phsysical light emixer, creating a real photo of your 3D model.
I need 3 days, 1 to make the model and feedback round, and get you green light to pass to the photography scene. And one more day to setting the light and rendering, a bit more time to do the final PSD retouch. The last day, its to be sure, and taking care, to final moment surprises.
Best regards
P
