I think what this means is that they don't want to be responsible for finding you clients. Perhaps you can be proactive and create a marketing plan and show the prospective employer that you know how to get clients or at least have a plan for it. I don't what type of place you are interviewing for but I'm sure if you are confident and can convince them you are able to get clients and even bring them clients making it a benefit for them to hire you, you will do fine. You could bring in references from other people in your life preferably not relatives that have received bodywork from you as well.
