Hi there,
I have good experience in 3d printing, and I am a sculptor, for these reasons, my humble application maid just be a good fit. I have some good example of faces on my profile, as well as testimonials.
My workflow include work in Zbrush, I do import the source images there, and work on the portrait. Biggest forms first, than pose, and then smaller, and smaller forms until I reach the desired level of details. Sometimes a portrait has a character, that is visible, even when you do not know the person I really try to catch that in my works. My price for one bust is between 50 to 70 USD depending on the complexity of the face. It can drop, if there is really a good amount of jobs, but for only one sculpt it is this. It can take 1 up to days of work. What I offer for the price is this: modelling of the face, modelling of a base, exporting printable STL files, giving source files, one print of the head in good resolution, daily updates, and positive attitude. Optionally a decimated version can be uploaded online, where any one of your choose can see the work from any side.
I love what I do, this is visible in my works, and I will be happy to discuss the project with you.
Kindly,
Valkan Pavlov.
