Very Smart on your part to learn everything you can before breeding. I unfortunately can't help you with any breeders in your area, but I do want to point out a website.
Canine Reproduction Video and Book on Breeding and Whelping dogs by Debbie Jensen for dog breeders and Whelping Supplies needed to deliver puppies. She is amazing!!! Very knowledgable and a lot of information on her website. As far as the tail docking and dewclaws...... If you think you have the stomach for it, go for it! I don't do my own, I have my vet do it.... but if you learn how to do it and think you can, do it. Some breeders on the site do do it themselves and could give your direction on how to do it yourself.
Best of luck to you and I hope that website helps. and Welcome to YT!
