I don't know of any breeders specifically in your area, but there are a couple of great places to start looking to find some and start communicating with them.
www.birdbreeders.com is probably the place to start first. You can search by species and then by state, and many private breeders post their current and upcoming clutches on this site. This is the place that I found my Lita's breeder (my blue Quaker), and I was able to write down the names/websites/emails of each individual breeder I found and then do some research on them, as well as sent them each an email to make contact with them. Lita's breeder responded right back to me, and we spoke back and forth for a good 2 months before she had a clutch start hatching, so it worked out well. There were a lot of private breeders on this site...
The next site I've found breeders on is
www.birdsnow.com This site is very similar to the first one, you can search for private breeders by species and then by state. I found my Cockatiel's breeder on this site 4 years ago, and again started communicating with her long before I ever made the 2 hour drive to go and pick Duff up.
There are obviously a bunch of websites that simply list bird breeders and aviaries, but the two above seem to be the most-widely used. The other place that I'd take a look at, especially for a Cockatiel as there are more breeders of them than other parrot species, is on your local Craigslist pages. There are a ton of breeders who post upcoming or current clutches on their local Craigslist pages, and this is actually how I found my Senegal baby, Kane. I had been searching for a hand-raised baby Senegal for months and couldn't find a breeder within 2 or 3 states of me (well, except for one that I ruled-out immediately), so I started expanding my search on Craigslist, and finally found Kane's breeder in North Carolina. I was able to check him out online after I spoke to him, as he'd been breeding parrots for decades, and I ended-up driving the 9 hours one-way to pick-up Kane about 3 months after I started speaking to him. With Cockatiels however, you're probably going to find many more breeders local to you, and the best way to do it is find the breeder, make contact with them, and then research them online.
Hopefully you can get some recommendations of Cockatiel breeders local to you from members here that know them and that have gotten their birds from them. Of course the other thing to consider looking at, when you're ready to actually bring a bird home, is at local Avian Rescues, as their are many, many Cockatiels out their in Rescues, I bet the Rescue I work at gets at least 3 or 4 Cockatiels each month on average.
