Yes you're right, these models are kind of specific. To be more accurate, these kinds of models are not to be found so much because they are very trend specific. The majority of furniture models found online can be put in roughly two categories: 1. Really clean design items, designed by renowned designers. 2. Very classical style models, often used in america. Which is nice but I see a lot of roughly the same models. Sometimes it laks diversity.
Luckily there are more and more models being made that are more trending, and 3D Sky is a great source! Unfortunately I cannot find these more trending models, yet.
Anyway, I think is probably too expensive to have someone model about 10 models for one project. What do you think modeling a detailed would cost, roughly?
