Market's lousy for flippers right now. DOM (days on market) is climbing rapidly in most areas, as are foreclosures. It's rapidly becoming more and more of a buyers market. And Coot's right, the good properties/information is already being sat upon by folks who have a lot more ready cash and credit to pick up properties faster, and are willing to accept a lot less profit than you (they've got low interest loans, or flat out cash, are General contractors/developers and don't have that overhead, etc). They can out-bid you in a heartbeat, and still make more profit off the property than you would.
Of course, you could always get into that world and try to find one of these individuals who's willing to take you in as an apprentice of sorts, giving them an extra pair of hands/brain in exchange for their knowledge and a hefty cut of the proceeds.
