Hi Lissa,
I'm from Jersey too. I got my yorkie from a breeder in PA and believe me it was not cheap. Most breeders in this area aren't cheap so your right to be looking in a rescue or a rehoming situation if you are on a tighter budget. I check petfinder.com alot just to see what's out there and yorkies do end up in shelters sometimes. Also there are rescues aren't here like United yorkie rescue and rescue me yorkie that might be able to help you out. And lastly we have this forum here:
http://www.yorkietalk.com/forums/forumdisplay.php?f=39 where people post threads about yorkies that they find at shelters or craigslist that need homes or they are rehoming their own yorkie.
Good luck on their search and i hope you weren't scared away.
