It's not the first time bud. lol. The first model a Friend of mine and I split. it was $585, and I sourced a 3D CAD eng that was close enough but still without a proper engine bay. Yes if i find someone willing to model some of my own IRL items i would probably pay up to 500.
only money created by the govt that is not real lol. Made up. I would suggest watching a bunch of Blender Tutorials on YT. You will become pretty decent within the first 1-2 years.
