Gonna have to talk to friends and coworkers. I've done this (mock interviews for people who are bad at interviewing) for friends and even friend-of-a-friends, but I wouldn't want to be on a searchable directory of such people.
Yeah that seems to be the common theme, "Ask friends and coworkers" I guess I need to do a bit more networking at meetups at such. Its been word of mouth from previous clients for all these years so I never bother to reach out to build a network.
