Ideas on where to offer chair massage

I'm going to a car dealership this week to offer chair massage to their employees or as a gift for their customers, but where else can I offer my services? I will be charging $1/minute, asking for 2 hours minimum to come to their office. I'm going to tell  them, they can reward their employees by having me there once a month and either the employer can pay or they can ask their employees to pay.

Massages will be 10 - 15 minutes each. I'm thinking about celebrations, anniversaries, perhaps for a business that is celebrating an anniversary or an employee appreciation day.. 

 Anyone have any ideas of where else I can offer chair massage? I'm thinkin of businesses, not parades or having a booth in an outdoor celebration. I'd like to come to a business like once a month, or every 3 months, or several places once a year..? My friend goes to her auto mechanic monthly and the owner pays for massage for his employees.

Thanks! Sandy
