Hello, how can the tennis coach find them? What if we don't get any news now?

Looking for a tennis coach, one is recommended by some tennis friends, and the other is a tennis forum like Donovan. Then, if you want to take the coaching certificate as a coach, I don't think it's very useful. Institutions like PTR and ITF are expensive and have few opportunities. And now many coaches look at teaching experience and teaching methods rather than a simple coaching certificate.
