Syag, beyond personal experiences, I researched all local frum and even modern schools, and heard from other people about other places. I spoke with a number of Rabbis and teachers both working in those schools and those who were just customers. I do understand that my knowledge is limited, of course. My suggestions are based what I know of halakhic approaches, and you are welcome to bring your own knowledge also. If you are not denying that halakha wants unlimited competition between teachers and all that is implied by that, then the question is how exactly this should be applied.
