Thanks for the responses.
Actually the coupon is through living social. The deal they wanted me to offer would have put me in the hole about 18k because i have to rent out space from the studio and they take 60% of the sales. They also have a 12 month expiration on the coupons and you cant limit how many you sell so i dont think i will be going with them but we will see.
You actually get business from craigslist? I didnt know they had a section for fitness type classes.
