It seems like usually by the time something like this gets into the mainstream, that it's usually too late to make a good profit on it. If you're making a 2% profit off $2million in sales, you're making $40K/year. If you're working with a lot of small items, I'm guessing it's not a "Just one hour a week!" kind of gig. So you can maybe make an okay living, but it's no miracle income.
