I am hiring a Zbrush artist who can do highend retouch work of a 3D scan using Agisoft's photoscan. Some of the 3D data might consist holes and noise but most should not be much of a problem. I would like the final data to be ultra high quality with UV masters done properly too. I will send .obj data for retouch of noise, and when the retouch is done, I will make a proper texture map using retouched obj data and send back the texture map for final retouch as well.
