I'm glad this got a second chance, because I really think it's a brilliant idea.<p>I just have a difficult time seeing how it could be cost-effective, without being eye-wateringly expensive.<p>Being able to detect forgeries requires some pretty intense domain expertise, and that tends to come with a lot of experience and schooling. Those folks don't run cheap. Very often, you need specialists in each domain. For example, you can't have a fashion purse expert determining whether an "antique" firearm (where forgery is a big problem) is fake.<p>I'd assume the biggest value would be to contract with auction houses or appraisers, where the workflow would be familiar. With regular users, the workflow would be all over the place, and I could easily see the whole thing taking hours, because the user keeps sending cruddy photos in a tungsten light, so the color can't be judged, or the focus is off.<p>But I guess if it's really just sending links to Amazon listings, things are fairly "standardized," so a number of assumptions can be made.<p>Nonetheless, this is not my area of expertise, and the OP insists that it is a viable service, making a profit, so I must offer kudos.
