I read it in several job advertisements:
‘Studio specialized on architectural visualisation is looking for 3D artist…’
What you are looking for is a 3D architectural visualiser.
If you are a gallery, specialized on digital art, then you could look for a 3D artist, to make an exhibiton for him/her or sell his/her art.
Artists make art, what meets their expectations.
Professionals make jobs/tasks, what meet your and your client’s expectations. Big difference.
