3D Modelling for commerical 3d printing

I want one or multiple (based on pricing) 3d models made, so that I can print them and sell them as full resin models for things like tabletop games. I will also try my hand at painting them myself if that matters at all. I've never done things like this before, but I want to avoid copyright issues. I will attach a few images of *reference* material. I'm sure we don't want to copy them directly, just examples for inspiration and to give an idea of what I want.

I understand different designs could make the price vary widely, but I am more than happy to discuss it. I apologize in advance for my ignorance around the subject. Trying to learn though!
