Dog Health Questions: When looking for a quality dog trainer?

I actually asked this question earlier in the day with no luck some people in the morning are no help and very negative.

So I have gone through about 3 different dog trainers each time learning something new and a fact I absolutely hate dog trainers who are not personable. I have had dog trainers recommend techniques that after 3 or 4 weeks have not worked and they refuse to try anything else. I need someone who is flexible to my dog, but I obviously do not know what constitutes as a good dog train. What are some good questions to ask a dog trainer besides are you certified and what is your experience because I get that when I am telling them hey this technique is not working I get screamed at.

Now I know someone is going to say it is me but I honestly am a very nice person and I never give attitude especially if someone has more knowledge then I do. But after 8 weeks(3 different times) of training with a stubborn beagle using their techniques and 600 plus dollars I am a little irritated. Finally I started modifying the training using tips from other dog owners and observing my own dogs needs. I was able to train her about 90%, but I have been working on walking nice with her and she can do it around people she is fine but if she sees a dog, cat, squirrel, duck, leaf , well you get my point. She immediately goes into play mode crys, pulls, jumps. I never give in and I would like a trainers help just on this problem. I know there are one on one but I want a group because I want her trained with distractions she is perfect in our own back yard.

So what are things I should look for we searching for a good trainer, what are some questions to ask?

Choosing The Best Dog Training Treats

• There are several organizations that endorse trainers. Their websites are below. Just because a trainer is endorsed does not make them a good trainer, however this does give you a good start in finding a good trainer. Things that I look for in a trainer include:
  Length of time in training dogs;
  Number and types of dogs trained;
  Their success in dog training (I'm looking for people who have competed with their dog (s) in the obedience ring)
  Methods used;
  References from former and current students; and
  A passion for teaching.
  
  If I'm taking a class, I want to be able to sit in a class or two without my dog. I look to see how the trainer interacts with the people and the dogs. I look to see if the dogs are under reasonable control and that safety rules are being enforced. A good class trainer should be able to match the method to the dog and the owner. She should be able to handle problems that come up in class in an organized and competent manner. I look to see if the class itself is organized such as starting on time. If the instructor is using a demo dog, I watch how well she interacts with her own dog. I also stay away from box store (pet co pets mart) classes. They just are not that good.
  
  No matter who you get as a trainer, doing the homework is very important. This includes taking your dog out of the back yard and training him in other environments. Going to a training class once a week isn't going to solve your problem. The methods need to be followed every day on every walk.
