JoeW.  I know several instructors including myself who will spend time with a student before agreeing to put them in the class.  During that time, we will answer any questions a potential student has.  If a potential student asks for references, I will provide them.  If they want to know how many students I have worked with, I can provide that information.  But I also interview the student.  I have turned down students who didn't impress me with an open mind and a willingness to learn.  Learning is a two way street.  The instructor can only provide information.  If the student won't apply it, they will be wasting their money and time. (I've only had to turn down 3 out of the hundreds I have worked with.)
As for the instructors, only someone who is Advanced or Master level can recommend someone for the program. And they have to first be a student to show their instructor they can learn, and then assist in teaching under the supervision of an Advanced or Master instructor. And if they don't meet the standards, they aren't recommended.
If it is that difficult for you to make the decision whether or not to take lessons, maybe you aren't ready. Do your research, make some calls, talk to instructors. When you find the one you like, do more research. You need to have confidence in your instructor. If you don't, both the student and the instructor are set up for failure. But if, like most students, you go into it with an open mind, and a willingness to apply what you learn, it's a win-win situation.
