My understanding is that neither LivingSocial nor Groupon avail their discounts to "outcall-only" services. A new suite of services are cropping-up that might be better for you as a service provider. Two notable ones include http://www.mytime.com/ and http://www.prompt.ly

Also, I'd encourage you to speak with peers or even book massage appointments via different services and talk with the service providers about their experience before doing so yourself.

I have several friends who are body-workers who have expressed dissatisfaction with their experience with "daily deal" sites. The two apps I mention are much more a "personal calendaring" service for people who sell their time, mixed with some commerce components.

Hope this helps.
