Gemstorm gave great advice. I keep some links handy for folks starting their poodle search and I'll drop those below. It's not specific to service poos, but there's a lot of places to look at, some of which you may have already seen. After the poodle specific health testing, I'd think temperament will be your focus.
One site in particular, PoodlesOnline, lists adults when available as well as puppies.

These are AKC registered breeders but review their websites thoroughly. Look for OFA, CHIC health testing info in the site. If not on the website, ask the breeder to provide all health testing results and links (this will be on the dam and sire fyi). In fact, do that with any breeder you make contact with. A quality breeder will not hesitate to show the health documentation.

Another site with multiple breeders listed. Use the same caution.
Most of us aren't breeders and don't have poodles for the purpose of showing, they are our loving companions. We are grateful tho to the breeders who believe in their dogs and literally invest the time and spend the money to train, compete, show and health test their dogs without thought of profit, so we can have our healthy and well bred pets.
There is a sub forum Poodle Breeder Directory where you can find or start discussions of breeders recommended, and some, not so much. They're listed at the top of Poodle Talk.
If you use the Search at the top of any page, use Advanced search for breeders in your area.
Contact a few breeders to introduce yourself. Even if they don't have or don't offer what you're looking for, it can be a close knit community. They may know where to refer you.
