I know a guy that does this by going to auctions and selling mostly antiques, but I haven't asked how he really does it, and I just met him really. How do you go about doing this for a semi-living salary? I know you won't make a good living (or can you?), but for a "part-time" or college job, I think it would be OK. Anyone know details on how much you make or what it takes to get into it?
