I'm sorry to say Chemil but you are asking this in the wrong place. You have to understand that with this sort of economy, once you discover a good item to make money on, every other person that does it reduces your profits. If you find something that works, you hope you are the one and only person that knows about it. That's why nobody is going to post their secrets here where everybody can read them and bottom out the market.
You can ask your friends or your LS which may be able to give you some tips but your best bet is to do your own research.
