Learn about positioning (market segmentation, differentiation). Think about what clients want, resp. what your ideal client would see as ideal service. Do they care about how good/pretty your designs are? Or maybe do they care about making money? They care about achieving a goal with that design - getting more users, building their trust, converting them, ... Do they know how to achieve all that? Probably not. How do you help them with it? What are they afraid of? (missing deadlines, overspending, lack of visibility into what you're doing, having to handhold you too much). How do you overcome that? How do you communicate it? Network. Find your ideal clients. Approach them. Read comments of HN users such as patio11. Check out what Ramit Sethi has to say (and many others).
