Furniture made

Hi I am adding furniture to a 3d model and finding it hard to track down certain pieces.
I have asked brands if they can supply the Sketchup or CAD but they don’t have them and I am definitely not skilled enough to create them and don’t have the time currently. I can adapt certain items but not all!
So, can anyone recommend Sketchup stores who make and sell these files or somewhere I can go to purchase reasonably? For instance the Belinda Chair by Cattelan Italia. Thanks.

Might be better to post in the Commercial and Collaboration category and hire someone to model those pieces for you.

Thanks
