My wife and sister in law are shadchanim, but they’re both in eretz yisroel. My wife is less active now as well.
To be honest, if those could e-mail the standrad info, that would probably make things much simpler. Those original first time long phone calls, then writing things down in a notebook. This way everything gets written down originally, can forward to other shadchanim. No wasting time if we don’t have anything, etc.
