good teachers like a needle in a haystack?

A school principal recently expressed her number one lament every school year---finding GOOD teachers. According to her it is hard to advertise for more students to increase enrolment because there are no real good teachers available to teach the students. She did not like the idea of just hiring ANY teacher. She wants good teachers to teach in her school---which is a real big problem by the way considering the fact that many graduates of education courses do not know how to speak English. Which is a big problem, really. Looking for good teachers is like looking for a needle in a haystack.
