I would be cautious about dealing with that guy. I was helping him to get some parts 3D printed, and once it came time for him to pay me for the parts, he never did and just stopped communicating.
Also, I was working on a custom figure run with a sculptor who had commissioned Brandon to create leather goods, a holster, gunbelt, satchel, etc. We were very close to completion, clothing sets were done, heads and hats were cast, we just needed the leather goods. The way it was told to me, the sculptor paid Brandon for a metal tool to stamp out the leather parts, but Brandon broke the tool and could not complete his end. He didn't have the money to replace the tool and obviously the sculptor wasn't going to pay him again, so the run just stopped. Pretty frustrating for me personally, as it was a passion project of mine.
