Know-How Exchange : Strategy

Hello there, me and my wife opened a salon about 2 years ago. We have a year left on our lease. In all honesty we really find it hard to get people to rent booths off of us, but we really haven't advertised lately. The whole inside is remodeled. When we first opened we pulled out all the stops. Flyers,news papers,cards etc. but it just didn't generate what we had hoped for. We really want to keep it. I work full time and so does she, not at the salon. She has all the credentials necessary to be there herself but at this point we Would just want people to rent the booths for extra income. It's a small spot ,two booths, but the inside is great. Please help, THANKS!
