Good luck. There are TONS of Pits down here in Broward, probably due to them being banned in Palm Beach and Dade counties. I got my boy for pretty cheap though, his mother was a Red Nose, father a Blue. However, it seems that the big money at the moment is geared towards BLUES, particularily of the Gotti, Razors Edge, and Gray Fox lines and these dogs are often huuuuge. While a massive, huge-headed Pit looks impressive, I think it actually defeats the overall purpose of a Pit in being an agile, athletic, and medium-sized dog. I call those dogs Hippos
. As for making a bit of money, well, I don't think you'll make THAT much on just 1 litter or 2 of pups...you have to factor in shots, vet visits for the mother post-birth, food, space, accessories.
Hope they find good homes, there are an overwhelming amount of Pit Bulls and Pit Bull mixes in shelters across the US. They make great family dogs and are extremely intelligent.
