Liz - my chiropractor does ultrasound and a version of triggerpoint & massage {NIMMO} - plus low level laser.
and his office space is shared with a massage therapist.

around here quite a few chiros have a massage therapist available.

maybe you can find a DC that will do only what you ask for, or a freelance massage/PT that will do it???

amazing what you can find on craigslist
