Hi srummelil, are you still looking for help with the 3D office props? I am Erik Jansen, working remotely from the Netherlands. The ordinary desks, filing cabinets and mugs in your 1975–1995 office setting are the part I could help with.
Here is an independent 3D object study: https://erik-jansen-3d-studies.medospect.chatgpt.site . I use AI-assisted modelling tools and check the geometry and exported files.
For an agreed first set of three simple props, my indicative fee would be EUR 200–350, depending on their detail and materials. Which objects would you prioritise, and what reference style, polygon/texture limits and Godot import format do you need? I would confirm the exact scope and price from those requirements before starting. Happy to discuss the initial brief here if that works for you.
