Here are some more suggestions:
1. Join a networking group.
2. Build a good web site that will bring your business.
3. You hire a marketing person to help you, but it’s more costly.
4. Visit as many businesses around your area and let them know about yours. Best places to start would be other physical therapy locations, chiropractors, medical offices, places where sports league games are taking place (parks), massage and acupuncture businesses and if you want to expand even more then visit some of the small or larger companies/corporations that like to offer wellness programs for their employees to let them know you can work with them or offer some new classes and programs.
5. Run a deal with one of those daily sites like Groupon, to reach a much larger audience and get some free advertising. Just be sure what you want to offer and what your capacity for new clients is.
I hope this helps.
