You didn't mention that licenses are required, so I guess you are fine making money with unlicensed/stolen content?
The OP did not specify that I've seen and so far the images on the demo are random watermarked photos found online.
However, the set of 200 I'm providing cannot be found anywhere else online except from other buyers, if there are any and if they do something with them, I also have the 2257 documents to go with each model set.
