Hi — your request for an endless, slightly-wrong 1975–1995 office suggests a useful fixed-scope test before anyone commits to ongoing production. I have prepared a small original six-object starter: a work desk, swivel task chair, five-tier shelf, low equipment cabinet, 3 m floor module and 1.8 m wall module. Every object is supplied in GLB and OBJ/MTL with metric dimensions and preview images. The geometry is original and contains no third-party meshes, scans or textures.
I can offer the completed starter as a non-exclusive commercial licence for USD 120, with no custom-work or continuing-support commitment. If the visual direction is not close enough, there is no obligation to proceed. I can share the six-object preview here first.
