I usually contact them with a short email outlining what I look for. I don't like calling strangers on the phone either so I email or text. Compose a general message (with minor modification if I can tailor it based on info on the therapist) including basic questions if relevant (for example insurance, fee) and send it out. See if/how they respond. Then set up a consultation with a few that look promising and go for it. Many therapists offer free first appointment, this is also something that can be inquired upon first contact.
