I got my certification in July, having a hard time finding clients

I initially set out to find a position with a gym, almost accepted with LA Fitness but then decided it would be best to train out of my home. I have a full gym and at one point had 6 clients (honestly that is all I wanted). I unfortunatly am not available at night since my husband works shift work and I have children who still need to be transported. I am down to 1 client and am having a hard time getting more. I have been searching for a position locally, have sent out resumes, etc but it seems most places just want to "rent" me space. I am getting very frustrated and discouraged. Any words of advice?
