Some more details would help to give a better answer. I am self employed and not currently in immediate need of needing someone but I periodically check the state board website, in PA you can search the list of who has a current state license. It doesn't really tell you if people are looking for work but for me  I live in a small area so I'm familiar with most of the names or I'll ask others if they know the person and if they're available for work. Another thing I do is contact the local school, they have someone designated to keep up with current resumes of graduates looking for work and she emails them to me. Since I'm not in a hurry, I've been picky and haven't found someone that I feel I've "clicked" with yet. It is hard being from a small area, and I think most graduates expect to be handed a full book of clients. I know how hard I worked to be able to get out on my own but finding someone with those same goals and values is really hard when you have a limited selection.

If you're running a clinical level practice, what other training do you want them to have above the state standard? In my experience, basic training is insufficient for clinical level work. When I was running a clinic, I wanted 500 hours base, continuing ed classes in MFR, NMT, lymph drainage, or sports massage, and 3-5 years in practice. We were a primarily clinical practice, but would convert our clinical patients to massage clients when their treatment plan was finished.  I wound up hiring a recent grad with a year in practice, and a strong interest in the clinical side.  She was doing lots of independent study, and had a good work ethic.  I started her on the maintenance side, and gradually built up her training, experience & analytical skill levels so she could begin clinical work. It worked very well, but finding that person can be hard.

Say you want a person with certain modalities (Myofascial, NMT, etc) you may want to see who is teaching those CEU courses locally. Ask them if you can rent/buy their mailing list and send out a mailer. It will put your information out in front of the qualified people you need. I would double check that the instructor received approval from the student to share their contact information with you and avoid sticky situations.

Depending on the state you live, I *think* some will allow you to rent/buy their membership list and you can do the same thing.

You may also put out job posting at a massage school (that has full certifications that specializes in your modality needs) and advertise there.Of course, a recent grad might not be ideal, but if they are trained specifically in what you need it might be helpful. In the area where I went to school (and all the local schools) everyone graduated with a certification in NMT. If your local school don't teach what you're looking for try and advertise out of state - you never know if a recent grad or a seasoned alumni is moving into your area.
