3d STL file for 3d printing

I am in need of a 3D STL file for a toy that needs to be 3D printed. I am looking for high quality, precise results for the small size of this toy. The 3D model needs to be designed specifically for 3D Printing so that when it is printed, I get exactly what I expect. This will require a professional who is experienced in creating these types of 3D models. The finished 3D model should also be able to be imported into a 3D printer with minimal error. Please only apply if you have specific experience with designing STL files for 3D Printing as I am aiming for the highest quality product!
