Driver,
Sorry for busting your chops, let me see if I can help.
If I were in the market for a bulldog the first thing I would do is visit the Bulldog Club of America website:
http://www.thebca.org/
On the site, I would look for people in your area that are active in the club. It would appear they also have some sort of mentoring program:
http://thebca.org/bulldogmentors.html
Then I would look at the breeder referral list:
http://thebca.org/breedref.html
By getting in touch with mentors, breeders, and club members, I have no doubt that you will be able to find a fine reputable breeder, who confirms and health tests his stock.
I'm sure there are easier and less expensive ways to get a dog but this is the only method I would use. If you want to understand my process I'd be happy to explain it, but won't bore readers with the information who aren't interested.
Just remember, there as many ways to buy dogs as there are to buy cars. Saving some money in the short term might cost you more in the long term.
Breed clubs exist for a reason and at the very least, you can hope to be referred to someone who REALLY cares about the wellness of the breed and has interests in constantly trying to improve it with each liter.
Good luck and let us know how it goes.
B
