For me personally, I look for a PhD because I have a PhD and I need someone who is very knowledgeable about serious mental illness. However, I have worked with good PhDs and not so good, or even underprepared, PhDs. This week I have started looking for a therapist for my teenager and I am looking for a master's level social worker.

So I guess what I am saying to the OP is to pursue what you see as your calling, who you want to be your clientele, and what issues you want to become an expert in, and there will be clients interested in what you have to offer.
