Detailed 3D Models

I know that this thread is for in-engine but I recently have been struggling with being able to make detailed 3D models for my game. I was wondering if there is any type of repository or any way to hire someone to do it. I’ve found resources like Quixel Megascans but none of these have exactly what I’m looking for. The models I need are a car similar to the DTM off of Back to the Future, a more futuristic looking flying car, and a hover bike. Textures and materials don’t matter, I’d preferably like to that on my own,

There’s a “looking for work/giving work” forum down below that you could give a try to. Custom high end art work isn’t cheap though…

I already posted on there. I just haven’t hear any responses yet. I just thought I might post here as well if there was anything else.
