Accord,
I did some research and the Roice-Hurst Humane Society in Clifton will give your dogs their shots for $10.00. Also, they help out with spaying and nutering. Here is a link to them with there phone number. Maybe you could call and talk to them.

I also have another link I would like you to take a look at. Its Pit Bull Sad Reality. I should warn you that a lot of the pictures on there are very graphic. But it does show you how so many people in this world treat the pit bulls. The site has a lot of great info on it. It might make you guys stop and think about bringing more pits into the world. There are so many that are unwanted in shelters that need homes. Why bring more into the world when so many need adopted from the shelters!?! As, you probably know the pit bulls are having a tough time so many people hate them and want them gone. We as pit bull owners have to change that and give them the good name that they so deserve. Please help to do that for the pit's sake. Your puppies are adorable and they deserve the best in life and it's up to you to give that to them.

Here is the link to the pit site.
