Hi Michael,
I read the entire description your project, and i am happy to tel you that, I am doing the exact same process ( not withe that game, but with a game called Racedriver grid and Skyrim) ( check my portfolio).
* I CAN EXTRACT THE MODELS FROM THE GAME IT SELF, unlike other people, who model it on their own ( other people may have imperfections due to this reason ).
And if the models are low poly, i can edit them to make it more realistic.
And the reason I am quoting this at a lower price is because, it really isn't that big of a job.
Plus I did make my own 3D printer, so I am aware of the minimum calculations for the radius of the curves and clearance need for the print to look good. I can also give you the .gcode file for the printer ( I will need the model or specifications of the printer to generate a gcode file) that you are using.
And if you want, i can have poster sized high-resolution, photo-realistically rendered pictures of the characters.
Looking forward on working with you.
Best regards.
Roman.
